Evolution of dispersal and the analysis of a resource flourished population model with harvesting Science Direct, 8 May, 2024 Publication Type: Journal View Summary/Abstract , Publication Link
This study explores a spatially distributed harvesting model that signifies the outcome of the competition of two species in a heterogeneous environment. The model is controlled by reaction-diffusion equations with resource-based diffusion strategies. Two different situations are maintained by the harvesting effects: when the harvesting rates are independent in space and do not exceed the intrinsic growth rate; and when they are proportional to the time-independent intrinsic growth rate. In particular, the competition between both species differs only by their corresponding migration strategy and harvesting intensity. We have computed the main results for the global existence of solutions that represent either coexistence or competitive exclusion of two competing species depending on the harvesting levels and different imposed diffusion strategies. We also established some estimates on harvesting efforts for which coexistence is apparent. Also, some numerical results are exhibited in one and two spatial dimensions, which shed some light on the ecological implementation of the model.

A numerical investigation on forced convection heat and mass transfer performance in a right triangular cavity Elsevier, International Journal of Thermofluids, 2024 Publication Type: Journal View Summary/Abstract , Publication Link
The objective of this numerical study is to examine how different Reynolds numbers impact heat and mass transfer in an unsteady forced convective two-dimensional flow within a right-angle triangular cavity. The lowest surface of the enclosure is held at a fixed temperature and concentration, whereas the slanted surface is taken to be a cool surface. Furthermore, the cavity's left wall is adiabatically positioned to move in two directions: upwards (aiding flow) and downwards (opposing flow), with a constant speed being maintained. The partial differential equations that govern the system are converted into a non-dimensional form through a straightforward transformation. The finite-element scheme is employed to solve these dimensionless equations. The analysis facilitates the investigation of the belongings of the Reynolds number on the heat and mass transfer appearances by using streamlines, isotherms, and isoconcentration lines. It is initiated that the temperature spreading as well as concentration within the cavity depends strongly on the Reynolds number. Moreover, the motion of the moving wall influences the patterns of fluid flow, temperature, and concentration fields. This study provides a comprehensive investigation into heat and mass transfer behavior occurring within a lid-driven right-angled triangular cavity moving in two opposite directions for aiding flow and opposing flow respectively.

Analysis of mixed convection under radiation and magnetohydrodynamics utilizing Kerosene-CNT nanofluid in a lid-driven cavity Elsevier, International Journal of Thermofluids, 2024 Publication Type: Journal View Summary/Abstract , Publication Link
The main objective of the study is to investigate the fluid flow pattern and thermal behavior of time-dependent 2-dimensional lid-driven cavity flow in the presence of mixed convection. The square-shaped lid-driven chamber was filled with a nanofluid consisting of carbon nanotubes (CNT) dispersed in kerosene oil. A semicircular heater is positioned along the lower wall. The research also incorporates the examination of magnetohydrodynamics and radiation. The use of the Galerkin residual approach inside the finite element method is utilized to derive nonlinear dimensionless governing equations. The phenomenon of Brownian motion in nanoparticles is included into models that describe thermal conductivity and dynamic viscosity. A constant magnetic field with a magnitude of Ha = 10, a constant Reynolds number of Re = 100, and a constant radiation parameter of Rd = 1 were selected for the study. Additionally, a nanofluid concentration of 5 % was chosen. The study aims to investigate the impact of mixed convection by using variable Richardson numbers within the range of 0.1 ≤ Ri ≤ 10. The results are presented in the form of streamlines, isotherms, 2D and 3D charts, illustrating the temporal variations of diverse thermophysical parameters. The investigation reveals that the magnitudes of the drag force and pressure gradient are comparatively greater in the scenario of natural convection. The drag force is 2.8 times greater in the Ri=10 case compared to the Ri=0.1 case. The velocity magnitude is found to be 18 times higher in the Ri= 10 case than in the Ri= 1 case. The Nusselt number has an elevated value as the Richardson number is augmented in conjunction with the dimensionless time (τ).

Dynamical analysis of optical soliton solutions for CGL equation with Kerr law nonlinearity in classical, truncated M-fractional derivative, beta fractional derivative, and conformable fractional derivative types Elsevier, Results in Physics, 2024 Publication Type: Journal View Summary/Abstract , Publication Link
The study of optical soliton solutions plays a vital role in nonlinear optics. The foremost area of optical solitons
research encompasses around optical fiber, telecommunication, meta-surfaces and others related technologies.
The aim of this work is to integrate optical soliton solutions of the complex Ginzburg-Landau (CGL) model with
Kerr law nonlinearity, also showing the effect of diverse fraction derivative and comparing it with the classical
form. Here, the local derivative is used as the conformable wisdom known as the truncated M-fractional derivative, beta fractional derivative, and conformable fraction derivative. We also deliberated on some assets
satisfied by the derivative. The CGL model is useful to describe the light propagation in optical communications,
optical transmission, and nonlinear optical fiber. Under the right circumstances, the affectionate unified scheme
is implemented for the complex Ginzburg-Landau model to generate the optical wave pattern. For α1 = 2α2, the
unified scheme generates the solution of CGL model in terms of hyperbolic, trigonometric, and rational function
solutions. This scheme provides some novel optical solitons such as periodic waves, periodic with rogue waves,
breather waves, different types of periodic rogue waves, a singular soliton solution, and rogue with the periodic
wave for the special value of the free parameters. For α2 = − ρ+6α1
8 , the unified scheme generates the solutions of
CGL model in terms of hyperbolic, trigonometric, and rational function solutions. This scheme offers some fresh
optical solitons such as periodic rogue waves, multi-rogue waves, double periodic waves, and periodic waves. In
numerical argument, the wave patterns are offered with 3-D and density plots. To test the stability of the obtained solutions, we show diverse fractional forms such as beta time fractional, and conformable time fractional
derivative and compare these fractional derivatives with their classical form in 2D plots. The investigation reveals innovative and explicit solutions, providing insight into the dynamics of the related physical processes. This
paper provides a comprehensive examination of the obtained solutions, emphasizing their distinct features and
depictions using unified technique. These findings are especially advantageous for specialists in the fields of
nonlinear science and mathematical physics, providing significant insights into the behavior and development of
nonlinear waves in various physical situations.

Artificial neural network (ANN) analysis on thermophysical properties of magnetohydrodynamics flow with radiation in an arc-shaped enclosure with a rotating cylinder Elsevier, Heliyon, 2024 Publication Type: Journal View Summary/Abstract , Publication Link
The objective of this research is to examine the thermophysical features of magnetic parameter (Ha) and time step (τ) in a lid-driven cavity using a water-based Al2O3 nanofluid and the efficacy of ANN models in accurately predicting the average heat transfer rate. The Galerkin weighted residual approach is used to solve a set of dimensionless nonlinear governing equations. The Levenberg-Marquardt back propagation technique is used for training ANN using sparse simulated data. The findings of the investigation about the flow and thermal fields are shown. Furthermore, a comparative study and prediction have been conducted on the impact of manipulating factors on the average Nusselt number derived from the numerical heat transfer analysis. The findings of the research indicate that, in the absence of magnetohydrodynamics, a rise in the Hartmann number resulted in a drop in both the fluid velocity profile and magnitude. Conversely, it was observed that the temperature and Nusselt number exhibited an increase under these conditions. The mean temperature of the fluid rises as the Hartmann number drops, reaching a peak value of 0.114 when Ha = 0. The scenario where Ha = 0, representing the lack of magnetohydrodynamics, shows the highest average Nusselt number, whereas the instance with Ha = 45 presents the lowest Nusselt number. The ANN model has a high level of accuracy, as seen by an MSE value of 0.00069 and a MAE value of 0.0175, resulting in a 99% accuracy rate.

Dynamical exploration of optical soliton solutions for M-fractional Paraxial wave equation The Public Library of Science (PLOS) , PLOS ONE, 2024 Publication Type: Journal View Summary/Abstract , Publication Link
This work explores diverse novel soliton solutions due to fractional derivative, dispersive, and nonlinearity effects for the nonlinear time M-fractional paraxial wave equation. The advanced exp [-φ(ξ)] expansion method integrates the nonlinear M-fractional Paraxial wave equation for achieving creative solitonic and traveling wave envelopes to reconnoiter such dynamics. As a result, trigonometric and hyperbolic solutions have been found via the proposed method. Under the conditions of the constraint, fruitful solutions are gained and verified with the use of the symbolic software Maple 18. For any chosen set of the allowed parameters 3D, 2D and density plots illustrate, this inquisition achieved kink shape, the collision of kink type and rogue wave, periodic rogue wave, some distinct singular periodic soliton waves for time M-fractional Paraxial wave equation. As certain nonlinear effects cancel out dispersion effects, optical solitons typically can travel great distances without dissipating. We have constructed reasonable soliton solutions and managed the actual meaning of the acquired solutions of action by characterizing the particular advantages of the summarized parameters by the portrayal of figures and by interpreting the physical occurrences. New precise voyaging wave configurations are obtained using symbolic computation and the previously described methodologies. However, the movement role of the waves is explored, and the modulation instability analysis is used to describe the stability of waves in a dispersive fashion of the obtained solutions, confirming that all created solutions are precise and stable.

A variety of soliton solutions of time M-fractional: Non-linear models via a unified technique The Public Library of Science (PLOS) , PLOS ONE, 2024 Publication Type: Journal View Summary/Abstract , Publication Link
This work explores diverse novel soliton solutions of two fractional nonlinear models, namely the truncated time M-fractional Chafee-Infante (tM-fCI) and truncated time M-fractional Landau-Ginzburg-Higgs (tM-fLGH) models. The several soliton waves of time M-fractional Chafee-Infante model describe the stability of waves in a dispersive fashion, homogeneous medium and gas diffusion, and the solitary waves of time M-fractional Landau-Ginzburg-Higgs model are used to characterize the drift cyclotron movement for coherent ion-cyclotrons in a geometrically chaotic plasma. A confirmed unified technique exploits soliton solutions of considered fractional models. Under the conditions of the constraint, fruitful solutions are gained and verified with the use of the symbolic software Maple 18. Keeping special values of the constraint, this inquisition achieved kink shape, the collision of kink type and lump wave, the collision of lump and bell type, periodic lump wave, bell shape, some periodic soliton waves for time M-fractional Chafee-Infante and periodic lump, and some diverse periodic and solitary waves for time M-fractional Landau-Ginzburg-Higgs model successfully. The required solutions in this work have many constructive descriptions, and corporal behaviors have been incorporated through some abundant 3D figures with density plots. We compare the m-fractional derivative with the beta fractional derivative and the classical form of these models in two-dimensional plots. Comparisons with others’ results are given likewise.

Modulation instability and comparative observation of the effect of fractional parameters on new optical soliton solutions of the paraxial wave model Springer Nature, Optical and Quantum Electronics , 2024 Publication Type: Journal View Summary/Abstract , Publication Link
This work focuses on the study of the paraxial wave model with a space–time fractional form. This model has more importance for describing light propagation in nonlinear optical fibers and telecommunication lines. The main aim of this work is to observe the effect of the fractional parameters and compare the truncated
-fraction with the beta-fraction, conformable fraction form, and classical form of the PW model. For this observation, we applied the Simplest equation technique to acquire analytical solutions to the space–time (spatiotemporal)
-fractional paraxial wave model. We are able to acquire several new optical soliton solutions, including periodic waves, kink-type waves, rogue-type waves, and several novel periodic waves, by providing the appropriate fractional parametric values. These solutions have significance for shedding light on a number of physical phenomena in the realms of optical fiber and communication sciences. The diverse values of fractional parameters and the three-dimensional and contour plot graphs of certain chosen solutions are depicted, which are the most accurate physical characterizations of the outcomes. We also sketch the comparative graph of diverse fractional forms and the classical form of the paraxial wave equation in two-dimensional plots. Consequently, our findings represent an important breakthrough in this complex area and help further develop our comprehension of the behavior of solitons.

Electroosmotic flow in ternary (TiO2-SiO2-Al2O3) blood-based sutterby nanomaterials with bio-active mixers Elsevier, International Journal of Thermofluids, 2023 Publication Type: Journal View Summary/Abstract , Publication Link
Medical scientists, clinicians, and bioengineers are fascinated in the detection of blood flow pattern through cardiovascular system because it is employed to diagnose the human circulatory disorders such as atherosclerosis. This work is dedicated to the mathematical modeling for the blood flow through human circulatory regimen with electroosmotic force, tri-hybrid nanoparticles, swimming microbes and activation energy. A novel ternary fluid is prepared by dispersing titania, silica, and alumina nanoparticles in pure blood. It is a well-known fact that blood is regarded as incompressible non-Newtonian fluid, due to which Sutterby fluid paradigm is regarded to detect the shear-thinning characteristics of blood precisely. To describe the electroosmotic flow, Poisson-Boltzmann expression is used. The novelty of the appraisal is the incorporation of electroosmotic force on blood flow containing with microbes and three distinct nanoparticles. Appropriate dimension-free variables are utilized to modify the dimensional system into dimension-free version. An unraveller approach, finite-difference is assigned to evaluate the numerical solution of dimensionless system accompanied by stability and convergence. The computed numerical results are sketched versus crucial factors and explored through graphs and tables. Electroosmotic variable enhances the motion of ternary blood nanofluid. Higher exponential heat source variable strengthens the thermal borderline wideness. Heat transport rate is weakened via higher estimation of thermo-migration and random motion variables. Decay in mass transport rate is noticed for thermo-migration factor. Peclet number weakens the motile microbe's density. Bio-active Lewis number strengthens the density number of motile microbes. This study is extremely worthwhile in medical domain such as cancer treatment, heart surgeries, tumor treatment, microbial fuel cells, and microfluidic systems.

Dynamics of chemically reactive Carreau nanomaterial flow along a stretching Riga plate with active bio-mixers and Arrhenius catalysts Elsevier, Heliyon, 2023 Publication Type: Journal View Summary/Abstract , Publication Link
Nanomaterial flow has fascinated the concern of scientists across the globe due to its innovative applications in various manufacturing, industrial, and engineering domains. Bearing aforementioned uses in mind, the focal point of this study is to examine the Carreau nanofluid flow configured by the Riga surface with Arrhenius catalysts. Microorganisms are also suspended in nanofluid to strengthen the density of the regular fluid. Time-dependent coupled partial differential equations that represent the flow dynamics are modified into dimensionless patterns via appropriate non-dimensional variables, and handled through an explicit finite difference approach with stability appraisal. The performances of multiple flow variables are examined graphically and numerically. Representation of 3D surface and contour plots for heat transportation and entropy generation are also epitomized. The findings express that the modified Hartmann number strengthens the motion of nanomaterial. Reverse outcomes for heat transport rate and entropy are seen for the radiation variable. Concentration diminishes for chemical reaction variable. Activation energy enhances the concentration of nanomaterial, whereas reduction happens in the movement of microbes for bio-Lewis number. Greater Brinkman variable heightens the entropy.

Parametric effects on paraxial nonlinear Schrödinger equation in Kerr media Elsevier, Chinese Journal of Physics, 2023 Publication Type: Journal View Summary/Abstract , Publication Link
In this study, we have considered the (2+1)-dimensional paraxial nonlinear Schrödinger (NLS) equation in Kerr media and used the (w/g) -expansion method. The g' and (g'/g2)-expansion techniques have been customized from the (w/g) -expansion method. We applied these two techniques to the paraxial NLS equation and found the optical soliton solutions. The optical soliton solutions are attained as the flat kink, kink, singular kink, peakon, anti-parabolic, W-shape, M-shape, bell, and periodic wave solitons in terms of free parameters. We have presented three-dimensional (3D), two-dimensional (2D) and contour plots of the obtained results and discussed the effect of the free parameters and nonlinearity of the equation by determining different parametric values, which have not been discussed in the previous literature. We have studied the impact of the Kerr nonlinearity and wavenumber on the travelling wave solutions. Moreover, we also analyze the streamlines pattern and instantaneous local directions of the wave profile. All wave phenomena are applied to signal transmission, magneto-acoustic waves in plasma, optical fiber art, coastal engineering, quantum mechanics, hydro-magnetic waves, nonlinear optics and so on. The achieved solutions prove that the proposed methods are very powerful and effective for modern science and engineering for scrutinizing nonlinear evolutionary equations.

The evolution of resource distribution, slow diffusion, and dispersal strategies in heterogeneous populations frontiers, 26 June, 2023 Publication Type: Journal View Summary/Abstract , Publication Link
Population diffusion in river-ocean ecologies and for wild animals, including birds, mainly depends on the availability of resources and habitats. This study explores the dynamics of the resource-based competition model for two interacting species in order to investigate the spatiotemporal effects in a spatially distributed heterogeneous environment with no-flux boundary conditions. The main focus of this study is on the diffusion strategy, under conditions where the carrying capacity for two competing species is considered to be unequal. The same growth function is associated with both species, but they have different migration coefficients. The stability of global coexistence and quasi-trivial equilibria are also studied under different conditions with respect to resource function and carrying capacity. Furthermore, we investigate the case of competitive exclusion for various linear combinations of resource function and carrying capacity. Additionally, we extend the study to the instance where a higher migration rate negatively impacts population growth in competition. The efficacy of the model in the cases of one- and two-dimensional space is also demonstrated through a numerical study.

Rotational effect of a cylinder on hydro-thermal characteristics in a partially heated square enclosure using CNT-water nanofluid Elsevier, Heliyon, 2023 Publication Type: Journal View Summary/Abstract , Publication Link
Rotating cylinder movement in a cavity flow is an exciting field of study in heat transfer. Considerable research has been carried out on rotating cylinders under MHD mixed convection in various types of enclosures. However, considering partially heated square enclosure and magnetic field using CNT-water nanofluid is very limited. This study's goal is to assess the hydrothermal phenomena in a square enclosure with a rotating cylinder. Simulation has been conducted for different rotational speeds (Ω) and dimensionless times (τ) to observe the thermal and fluid flow behaviour. The Galerkin Residual based finite element method has been used to conduct numerical calculations. The results are shown as isotherms, streamlines, and average Nusselt number at the cylinder wall. Moreover, the drag force at the moving wall, and the fluid properties such as the root mean square (rms) of velocity, the temperature, the vorticity functions, and the average fluid temperature are also presented. The heat transfer rate, drag force, rms velocity, and temperature increase with the rise of rotational speed and dimensionless time rise. Maximum vorticity occurs at Ω = 8 and τ = 1. The maximum vorticity function increases 12 times with the increasing rotational speed. Higher rotational speed leads to increased average fluid temperature. The case of Ω = 8, τ = 1 shows the most temperature variance, while Ω = 1, τ = 0.1 has the least. Increasing rotational speed results in higher drag force on the cylinder's surface. At Ω = 4, the drag force is 2.8 times greater than at Ω = 2. Overall, the fluid flow and thermal performance boost up while the rotating speed of the cylinder is higher.

Effect of Richardson number on transient double diffusive mixed convection: A thermo-hydrodynamic study Elsevier, International Journal of Thermofluids, 2023 Publication Type: Journal View Summary/Abstract , Publication Link
The goal of the paper is to evaluate the characteristics of the fluid flow, heat, and contaminant transfer in an indoor air environment. A two-dimensional ventilated space having a discrete heat and contaminant source at their mutually perpendicular position is constructed to conduct a numerical study. The governing equations with apprupirate boundary conditions of the model are evaluated by Galerkin weighted residual method. The transport characteristics are discussed for varying Richardson number 0.1 ≤ Ri ≤ 10 and dimension less time 0.1 ≤ τ ≤ 1 by the corresponding stream function, heat function, and mass function. Priority is given to analyzing the necessary factors – dependence on average Nusselt number, average Sherwood number, the average fluid temperature and mass concentration in the enclosure, along with the average temperature of the exit port to visualize the ventilation technique. Numerical output illustrates that – the attributes of the transport particles are largely determined by the interaction of the natural convection of heat and contaminant source with the mechanically forced flow of cool air. Results showed that mixed convection method is a better way to showcase efficient ventilation of the transport particles from the enclosure through a practical yet non-complex approach. This study will be a guide for design consideration for roof-based double-diffusive systems with partial heat and mass generation.

Influence of thermal conductivity on transient mixed convection in a vented cavity with a hollow cylinder and filled with CNT-water nanofluid Elsevier, Heliyon, 2023 Publication Type: Journal View Summary/Abstract , Publication Link
This study is aimed to perform a numerical time-dependent investigation thermal conductivity effect of the annular cylinder within a vented cavity using CNT based-water nanofluid. For demonstrating the effect of thermal conductivity, four distinct hollow cylinder materials such as Ks = 0.5(Plastic tiles), Ks = 0.84(Clay tiles), Ks = 1.1(Concrete tiles), and Ks = 2(Slate tiles) are introduced together with a suitable variation of dimensionless time (0 ≤ τ ≤ 1). The governing equations of the model with associated boundary conditions is solved using finite element based Galerkin's weighted residual method. Different contour plots for thermal and flow field transformation and mean Nusselt number, mean fluid temperature, bulk convective field temperature, temperature gradient, pressure gradient, vortices, and fluid velocity magnitude are presented for qualitative and quantitative thermal performance analysis. With the decrease of solid thermal conductivity, 27.3% thermal transport enhancement is noted from the heated surface of the cylinder. However, a 16.3% increase in the bulk fluid temperature has been recorded with the increase in cylinder conductivity. The numerical outcomes from this investigation propose a better thermo-fluid efficiency compared to the existing methodology which can be suggestive to engineers and researchers for designing heat exchangers, heat pipes, and other thermal systems.

On nonlinear optical solitons of fractional Biswas-Arshed Model with beta derivative Elsevier, Results in Physics, 2023 Publication Type: Journal View Summary/Abstract , Publication Link
The Biswas-Arshed (BA) model is an essential wave propagation model in nonlinear optics and optical fibers. In this manuscript, the enhanced (G'/G) -expansion method is taken into consideration. The BA model is used with this technique to locate visual soliton solutions. The solutions to the hyperbolic and trigonometric functions are determined using this technique. Each solution includes a large number of model and method parameters. The wave solutions are defined by the waves' character, which is determined by the three-dimensional (3D) and two-dimensional (2D) wave patterns with varying parameter values. The structure of the soliton shifts depending on the specific values of the parameters. These shifts are reflected in the 2D pictures that demonstrate the various soliton configurations. Finally, the obtained soliton solutions can be applied to high-speed data transmission to describe propagation pulses and to transmit light between two ends in optical fibers and communication systems.

On fractional order computational solutions of low-pass electrical transmission line model with the sense of conformable derivative Elsevier, Alexandria Engineering Journal, 2023 Publication Type: Journal View Summary/Abstract , Publication Link
In this study, we solve fractional order PDEs with free parameters that regulate wave motion in a low-pass electrical transmission line equation (LPET) using the unified technique. To convert the governing equation into an ordinary differential equation (ODE), we have used a simple linear fractional transformation. The unified technique can therefore be used to find various single and extracting wave solutions to the equation of attention. Using Maple-18 software, all of the established solutions are validated and verified. By selecting appropriate values for the fractional order and free parameters, the two dimensional (2D) and three dimensional (3D) profiles of some of the assimilation solutions demonstrating kink, singular kink, cross kink, bright-dark kink, lump type kink, anti-kink, dark-anti kink, singular periodic, periodic, singular soliton solutions are displayed. The effect of free parameters and fractionality on the dynamical properties of the precise and exploited solutions are graphically illustrated and discussed in detail. We have also compared our results to those found in the literature review. Wherever possible, the judgment demonstrates no significant differences between our realized and published solutions. The results of this investigation show that the adopting technique is both productive and powerful in extracting wave solutions to nonlinear evolution problems that arise in the areas of applied mathematics, mathematical physics, and engineering.

The modified extended tanh technique ruled to exploration of soliton solutions and fractional effects to the time fractional couple Drinfel'd–Sokolov–Wilson equation Elsevier, Heliyon, 2023 Publication Type: Journal View Summary/Abstract , Publication Link
The modified extended tanh technique is used to investigate the conformable time fractional Drinfel'd-Sokolov-Wilson (DSW) equation and integrate some precise and explicit solutions in this survey. The DSW equation was invented in fluid dynamics. The modified extended tanh technique executes to integrate the nonlinear DSW equation for achieve diverse solitonic and traveling wave envelops. Because of this, trigonometric, hyperbolic and rational solutions have been found with a few acceptable parameters. The dynamical behaviors of the obtained solutions in the pattern of the kink, bell, multi-wave, kinky lump, periodic lump, interaction lump, and kink wave types have been illustrated with 3D and density plots for arbitrary chose of the permitted parameters. By characterizing the particular benefits of the exemplified boundaries by the portrayal of sketches and by deciphering the actual events, we have laid out acceptable soliton plans and managed the actual significance of the acquired courses of action. New precise voyaging wave arrangements are unambiguously gained with the aid of symbolic computation using the procedures that have been announced. Therefore, the obtained outcomes expose that the projected schemes are very operative, easier and efficient on realizing natures of waves and also introducing new wave strategies to a diversity of NLEEs that occur within the engineering sector.

Wave profile analysis of the (2 +1)-dimensional Konopelchenko–Dubrovsky model in mathematical physics Elsevier, Partial Differential Equations in Applied Mathematics, 2023 Publication Type: Journal View Summary/Abstract , Publication Link
The (2 + 1)-dimensional Konopelchenko-Dubrovsky (KD) model and the modified version of the new Kudryashov (MVNK) technique are chosen in the current research to obtain the traveling wave solutions (TWSs). The obtained solutions represent the rich range of explicit solutions to the studied model. As a result, TWSs to the stated model are expressed as the different types of wave profiles such as the kink shape, bell shape, anti-bell shape, and W-shape wave profiles. The Hamiltonian function is found from the stated model and shown it as three dimensional, contour and phase plane in this manuscript. The effects of wave velocity and other parameters on the wave profile are also discussed. The obtained wave profiles are typically useful in applications how waves interact with high-dimensional systems in new, specialized structures. Additionally, the direction and position of solitons for changing other parameters can offer a clear-cut explanation of all the different features of wind and water waves. It is seen that the mentioned scheme is effective, potential and easy in mathematical physics. Finally, this study may be opened up brand-new avenues for further study and application in the fields of mathematical physics.

Numerical investigation with sensitivity study of MHD mixed convective hexagonal heat exchanger using TiO2–H2O nanofluid Elsevier, Results in Engineering, 2023 Publication Type: Journal View Summary/Abstract , Publication Link
This ongoing study is carried out to analyze the thermal performance with sensitivity study of a mixed convective hexagonal heat exchanger containing TiO2–H2O nanofluid. Magnetic force is regarded to be horizontal while all surrounding walls are adiabatic. The finite element method is used to simulate the regulatory equations. For the first time, response surface methodology is used to analyze the sensitivity of independent factors on a hexagonal heat exchanger. The findings are depicted for four parameters, Reynolds number (10 ≤ Re ≤ 200), Richardson number (0.01 ≤ Ri ≤ 10), Hartmann number (0 ≤ Ha ≤ 100), and nanoparticle volume fraction (0 ≤ φ ≤ 0.1) against velocity distribution, average Nusselt number (Nuav), streamlines, isotherm lines, and heatlines. The results indicate that the growing value of Re and φ strengthen the thermal performance of nanofluid whereas increasing Ha causes it to decrease. Moreover, φ and have positive sensitivity to the Nuav while Ha has negative sensitivity. When Ha is maintained at 0, the optimal value of Nuav reaches when Re = 200 and φ = 0.1. The use of TiO2–H2O nanofluid improves the water's heat transmission ability to 17.69%. Finally, the results of this study may offer advice for creating an effective mixed convective heat exchanger.

Dynamical simulation of wave solutions for the M-fractional Lonngren-wave equation using two distinct methods Elsevier, Alexandria Engineering Journal, 2023 Publication Type: Journal View Summary/Abstract , Publication Link
This study integrates the (1 + 1)-dimensional time M-fractional Lonngren-wave (tM-fLW) equation. This equation is useful to describe the phenomenon of the electric signals in telegraph lines at the source of the tunnel diode. To extract some soliton solutions, two reliable analytical techniques, the new form of modified Kudryashov’s and the simplest equation, are used to accomplish this job. By implementing these techniques, the obtained solutions are expressed as rational, exponential, trigonometric, and hyperbolic functions with some free constraints. For the special values of the constraints, we obtained w-shape wave, bell-shaped wave, linked rogue wave, and multi-bell wave solutions by the NMK method, and dark bell and bright bell-shaped wave, linked rogue wave, periodic rogue wave, and w-shape wave by the SE method. The graphical depiction analyzes these traits, demonstrating the validity and efficacy of the suggested techniques. The obtained solutions, which have never been done before and show a good balance between the nonlinear physical components, are what make this research novel. It is remarkable to perceive that the simplest equation technique and the new form of modified Kudryashov’s technique are relaxed, companionable, and authoritative mathematical tools to elucidate a non-linear model. The movement role of the waves is explored and the modulation instability analysis is used to discuss the stability analysis of the obtained solutions, confirming that all created solutions are accurate and stable.

A numerical appraisal of time-dependent magneto-convective thermal-material transfer over a vertical permeable plate Hindawi, March, 2023 Publication Type: Journal View Summary/Abstract , Publication Link
The objective of this work is to investigate the influences of thermal radiation, heat generation, and buoyancy force on the time-dependent boundary layer (BL) flow across a vertical permeable plate. The fluid is unsteady, incompressible, viscous, and electrically insulating. The heat transfer mechanism happens due to free convection. The nondimensional partial differential equations of continuity, momentum, energy, and concentration are discussed using appropriate transformations. The impressions of thermal radiation and buoyancy forces are exposed in the energy and momentum equation, respectively. For numerical model, a set of nonlinear dimensionless partial differential equations can be solved using an explicit finite difference approach. The stability and convergence analyses are also established to complete the formulation of the model. The thermophysical effects of entering physical parameters on the flow, thermal, and material fields are analyzed. The variations in local and average skin friction, material, and heat transfer rates are also discussed for the physical interest. The analysis of the obtained findings is shown graphically, and relevant parameters pointedly prejudice the flow field. Studio Developer FORTRAN 6.2 and Tecplot 10.0 are applied to simulate the schematic model equations and graphical presentation numerically. The intensifying values of the magnetic field are affected decreasingly in the flow field. The temperature profiles decrease within the BL to increase the value of radiation parameters. The present study is on the consequences for petroleum engineering, agriculture engineering, extraction, purification processes, nuclear power plants, gas turbines, etc. To see the rationality of the present research, we compare these results and the results available in the literature with outstanding compatibility.

The evolution of resource distribution, slow diffusion, and dispersal strategies in heterogeneous populations frontiers, June , 2023 Publication Type: Journal View Summary/Abstract , Publication Link
Population diffusion in river-ocean ecologies and for wild animals, including birds, mainly depends on the availability of resources and habitats. This study explores the dynamics of the resource-based competition model for two interacting species in order to investigate the spatiotemporal effects in a spatially distributed heterogeneous environment with no-flux boundary conditions. The main focus of this study is on the diffusion strategy, under conditions where the carrying capacity for two competing species is considered to be unequal. The same growth function is associated with both species, but they have different migration coefficients. The stability of global coexistence and quasi-trivial equilibria are also studied under different conditions with respect to resource function and carrying capacity. Furthermore, we investigate the case of competitive exclusion for various linear combinations of resource function and carrying capacity. Additionally, we extend the study to the instance where a higher migration rate negatively impacts population growth in competition. The efficacy of the model in the cases of one- and two-dimensional space is also demonstrated through a numerical study.

Ionanofluid flow through a triangular grooved microchannel heat sink: Thermal heightening Elsevier, 4 August, 2023 Publication Type: Journal View Summary/Abstract , Publication Link
With recent technological advances, thermal transport from different electronic and electrical devices is the most vital concern. The microchannel heat sink (MCHS) of liquid cooling is a useful device to remove over thermal load. Ionanofluid is a brand new and super potential cooling fluid for its ionic conductivity, non-flammability, negligible volatility, and high-level heat stability. In this research, the ionanofluid's velocity and thermal field characteristics through a triangular grooved MCHS are investigated using numerical tools. The combination of ionic liquid (IL) 1-Butyl-3-methylimidazolium Bis(trifluoromethanesulfonyl)imide [C4mim]NTf2 and propylene glycol (PG) is used as base fluid whereas graphene (G) and single-walled carbon nanotube (SWCNT) are chosen as hybrid nanoparticles to make the working ionanofluid. The governing equations of nonlinear partial differential equations describing the physical phenomena along with proper border settings are resolved by applying the finite element method (FEM). Different ratios of hybrid nanoparticles (G: SWCNT) like (1: 0, 1/3: 2/3, 1/2: 1/2, 2/3: 1/3, 0: 1) are suspended in the base fluid mixture. In addition, the base fluid mixture is assumed in different combinations of (IL: PG) as (100: 0, 50: 50, 0: 100). The numerical results are displayed in the forms of streamlines, isothermal lines, and rate of thermal transfer for the pertinent parameters namely forced convection (Re = 100–900) and solid concentration (φ = 0.001–0.05). Also, pressure drop, field synergy number, relative fanning friction feature, relative Nusselt number, and temperature enhancement efficiency are calculated. The results indicate that a higher heat transport rate is found using the IL-based ionanofluid with the highest solid concentration. Moreover, the higher forced convection enhances the thermal efficiency of MCHS. Two linear regression equations along with very good correlation coefficients have been derived from the numerical results.

Time-dependent thermal-material transfer of micropolar binary mixture fluid: Effects of Lorentz force and inclination SSRN, Proceedings of MARTEC-2022, 2023 Publication Type: Journal View Summary/Abstract , Publication Link
The effects of Lorentz force and inclined angle on time-dependent free-convective thermal-material transport by micropolar binary mixture of fluid passing a continuous permeable surface have been analyzed in this article. Using the local similarity transformation, the governing partial differential equations have been converted into ordinary differential equations. The shooting technique was then employed to solve non-dimensional ordinary differential equations with boundary conditions using the "MATLAB ODE45" software. The effects of emerging Lorentz force (M) and inclined angle (γ) on the fluid velocity, concentration, temperature, and microrotation have been investigated within the boundary layer. Other non-dimensional parameters in this study, such as Schmidt number, suction parameter, and Prandtl number are kept fixed at Sc = 0.22, c = 0.5, and Pr = 0.71, respectively. The numerically simulated result shows that the velocity falls for uplifting values of the inclined angle and Lorentz force. The skin friction coefficient decreases by 49%, and 20% due to increasing the values of inclined angle (00-600), and Lorentz force (1.0 - 4.0), respectively. The surface couple stress is found to be increased about 24%, and 44% with the upturning values of M (1.0 - 4.0), and γ (00-600), respectively. Through this research, the behavior of the fluid flow has been explored.

Numerical evaluation of overall efficiency for solar photovoltaic and thermal hybrid system IEEE, 2023 IEEE Conference on Power Electronics and Renewable Energy, 2023 Publication Type: Journal View Summary/Abstract , Publication Link
Climate change and the exhaustion of conventional energy sources with the growing demand for energy have caused concern among researchers all over the world. Renewable energy sources are a long-term alternative to our reliance on fossil fuels and reduce carbon emissions. Solar energy is radiant light and heat from the Sun that is harnessed using a range of technologies such as solar power to generate electricity, solar thermal energy, and solar architecture. Photovoltaic thermal (PVT) is a hybrid system, which includes both thermal and electrical energy generations. A 3D solar photovoltaic and thermal hybrid system is considered in this study where the encloser of the heat exchanger is fabricated from corrosion resistive stainless-steel sheet, and uncovered surfaces to the air of the heat exchanger are insulated using the glass wool. The fins manual air circulation and the channels are made of aluminium. The top side of the fins is bended and tightly attached to the lower back floor of the solar PV panel, wherein heat switch from the PV panel to the fins happens via the conduction technique. The equations of the heat transfer for PV layers such as for glass, cell, fins, heat exchangers, and laminar flow equation for the fluid domain are solved numerically applying the finite element method (FEM). Temperatures of air at the inlet-outlet and solar cell of the PVT system, are obtained for the variation of solar irradiance from 200 to 400 W/m2 using the weather situation of Bangladesh. Finally, the overall efficiency is calculated under different weather conditions in Bangladesh. The numerical results depict that the new layout of the heat exchanger efficiently transfers heat to the circulating air and the overall efficiency of the PVT is greater at the lowest solar irradiance of 200 W/m2.

Time-dependent magneto-convective thermal-material transfer by micropolar binary mixture fluid passing a vertical surface ThaiJo, Science and Technology Asia, 2023 Publication Type: Journal View Summary/Abstract , Publication Link
Time-dependent magneto-convective thermal-material transport by micropolar binary mixture passing a vertical permeable surface with chemical reaction, radiative heat transfer and thermophoresis has been studied numerically. The findings of this study have significant industrial applications in the production of molten polymers, pulps, fossil fuels, and fluids containing certain additives, etc. Applying the similarity analysis together with Boussinesq estimate, the governing PDEs have been modified into ODEs. These equations have been solved by applying shooting techniques with the help of “ODE45 MATLAB" software. The results of the numerical solutions of the problem involving velocity, temperature, concentration and micro-rotation are presented graphically for different dimensionless parameters and numbers, namely magnetic intensity, Damköhler number, thermophoresis, temperature dependent dynamicviscosity, thermal radiation, thermal Grashof number, solutal Grashof number, Prandtl number and Schmidt number. The magnetic intensity affects the velocity field only in the increase-decrease mode.An increase in Damköhler number and thermal radiation significantly enhances the velocity fieldswhile interrupting the rate of heat transfer within the boundary layer. The temperature dependent dynamic viscosity greatly enhances the velocity of the fluid but reduces the micro-rotation of the particles very near to the wall. Also, the increase of Prandtl number lessens conduction of heat while increasing the micro-rotation of the particles noticeably very adjacent to the surface.

Axisymmetric boundary layer slip flow with heat transfer over an exponentially stretching bullet-shaped object: A numerical assessment Science Direct, Heliyon, 2023 Publication Type: Journal View Summary/Abstract , Publication Link
The slip flow and thermal transfer inside the boundary layer are extremely significant for various problems in aerodynamics, wing stall, skin friction drag on an entity, high-level velocity aircraft, etc. The current research investigated the effect of the slip factor and shape factor on the axisymmetric bullet-shaped object by taking the viscous dissipation parameter and location parameter. The analysis is conducted for both fixed and moving bullet-shaped objects due to thinner and thicker surfaces. The governing equations are transformed into a system of ordinary differential equations using suitable local axisymmetric similarity transformations and solved by applying the spectral quasi-linearization method. A new correlation analysis is made for velocity and temperature gradients. It is observed that the boundary layer structure has no defined shape due to a thicker bullet-shaped object instead it forms a steep angle with the axis which is contradictory to the formation of the boundary layer. A negative correlation is observed for the parameters M, Ec, Q*, and s but a positive correlation is observed for the parameters such as Pr, P, λ, and ε. The surface thickness and stretching ratio significantly affect the fluid flow and heat transfer processes. It is also noticed that the thinner bullet-shaped object performs as a better cooling conductor compared to a thicker one. The skin friction is reduced in the case of a thinner bullet-shaped object compared to a thicker one. The present analysis reveals that the heat transfer rate and the friction factor may be helpful in industrial sectors for controlling the cooling rate and quality of the final product. This research brings forward to increase in the rate of heat transfer inside the boundary layer region. The result may help to design the various types of moving objects in the automobile engineering sector when the objects pass through the fluid.

A numerical analogy of improving efficiency for the PVT system in Bangladesh Hindawi, International Journal of Photoenergy, 2022 Publication Type: Journal View Summary/Abstract , Publication Link
Mathematical modeling of a three-dimensional PVT system is considered and solved using the FEM. Numerical simulation is applied to explore the influence of solar irradiance on the thermal energy, electrical power, and total efficiency of this system. Water is considered HTF. The solar irradiance, inlet fluid mass flow rate, ambient temperature, and partial shading are all chosen in the range of 200-500 W/m2, 30-180 L/h, 10-37 °C, and 0-30%, accordingly based on the weather condition of Bangladesh. The effects of irradiance, fluid flow rate, ambient temperature, and partial shading on temperatures of cell and output fluid, electrical power and thermal energy, electrical efficiency-thermal efficiency, and total efficiency of this system are examined. Numerical results show that increasing each 100 W/m2 solar irradiance enhances the cell and outlet temperatures and electrical and thermal energy by 2.17 and 0.54 °C and 20.7 and 113.3 W, respectively, and devalues the electrical, thermal, and overall efficiencies approximately 0.17, 0.67, and 0.83%, respectively. The cell and output water temperature reduce almost 0.6 and 0.83 °C, respectively; electrical and thermal energy rise by 0.30 and 3.07 W, respectively, and the electrical, thermal, and overall efficiencies escalate about 0.04, 0.4, and 0.44% for every 10 L/h mass flow rate increment. Due to each 10 °C increment of ambient temperature, cell and output water temperature increase 1.7 °C and 0.05 °C, electrical energy decreases to 0.9 W, thermal energy increases to 9.89 W, and electrical efficiency reduces about 0.1%.

Numerical analogy of bioheat transfer and microwave cancer therapy for liver tissue Wiley, Heat Transfer, 2022 Publication Type: Journal View Summary/Abstract , Publication Link
A numerical study of microwave cancer therapy for cylindrical-shaped liver tissue with an elliptical-shaped liver tumor has been carried out by this study. The time-dependent electromagnetic wave and the bio-heat transfer equations have been used as the governing equations and solved with appropriate boundary conditions using Galerkin's weighted residual scheme built-in finite element method-based COMSOL Multiphysics software. The coaxial applicator as well as the effects of different microwave input power levels (from 5 to 25 W), frequencies (from 0.7 to 5 GHz), and treatment time (from 0 to 1000 s) on hepatocellular carcinoma have been examined by this simulation and displayed graphically in terms of the microwave power dissipation, isothermal lines inside liver tissue, time-dependent profiles of temperature at different locations inside the tumor, specific absorption rate (SAR), and surface average transient temperature distribution of tumor tissue. The results demonstrate that microwave input antenna power and frequency have significant impacts on the temperature distribution and SAR values of liver tissue. When the microwave input power, as well as frequency, is increased, SAR and tissue temperature values also increase but the high temperature is harmful to healthy tissue. It is observed from the performed analysis that the mean temperature of the tumor cell is about 56.86°C at a time of 180 s using 10 W microwave input power and 2.45 GHz frequency.

Mathematical modeling of unsteady flow with uniform/non-uniform temperature and magnetic intensity in a half-moon shaped domain Science Direct, Heliyon, 2022 Publication Type: Journal View Summary/Abstract , Publication Link
The mathematical modeling of two-dimensional unsteady free convective flow and thermal transport inside a half-moon shaped domain charged in the presence of uniform/non-uniform temperature and magnetic effects with Brownian motion of the nanoparticles has been conducted. Thirty-two types of nanofluids in a combination of various nanoparticles and base fluids having different sizes, shapes, and solid concentrations of nanoparticles are chosen to examine the better performance of heat transfer. The circular boundary is cooled while the diameter boundary is heated with uniform/non-uniform temperature. An external uniform/non-uniform/periodic magnetic field is imposed along diameter. The powerful partial differential equations solver, finite element method of Galerkin type, has been engaged in numerical simulation. The numerical solution's heat transfer mechanism reaches a steady state from the unsteady situation within a very short dimensionless time of about 0.65. The thermal transport rate enhances for increasing buoyancy force whereas decreases with higher magnetic intensity. The uniform thermal condition along the diameter of half-moon gives a higher thermal transport rate compared to non-uniform heating conditions. The non-uniform magnetic field provides greater values of the mean Nusselt number than the uniform field. In addition, the outcomes also predict that a better rate of temperature transport for kerosene-based nanofluid than water-based, ethylene glycol-based, and engine oil-based nanofluid. The heat transfer rate is observed at about 67.86 and 23.78% using Co-Kerosene and Co-water nanofluids, respectively, with an additional 1% nanoparticles volume fraction. The blade shape nanoparticles provide a better heat transfer rate than spherical, cylindrical, brick, and platelet shapes. Small size nanoparticles confirm a higher value of average Nusselt number than big size. Mean Nusselt number increases 22.1 and 5.4% using 1% concentrated Cu-water and Cu-engine oil nanofluid, respectively than base fluid.

Effect of tin oxide/black paint coating on absorber plate temperature for improved solar still production: A controlled indoor and outdoor investigation Hindawi, International Journal of Photoenergy, 2022 Publication Type: Journal View Summary/Abstract , Publication Link
The ever-increasing water stress and availability of fresh drinking water are becoming a major challenge in rural and urban communities. The current high-end and large-scale technologies are becoming way more expensive and not friendly to the environment. In this regard, solar still is becoming a prominent and promising future technology due to its environment-friendly nature, less maintenance and operational costs, and simple design. The technological challenge regarding solar still is its low distillate yield. In this study, an attempt has been made to investigate the effect of tin oxide (SnO2) on the absorption surface of solar still towards improvement in sunlight absorption, which would lead to high distillate production rates. Various concentrations of SnO2, i.e., 0.5wt%, 1 wt%, 3 wt%, 5 wt%, 7 wt%, 10 wt%, 15 wt%, and 20 wt%, have been mixed in black and applied on the absorber plate to further optimize the suitable concentration. The experiments have been performed in both indoor (simulated) and outdoor conditions. An increase in surface temperature of absorber plate has been observed with increasing concentration of SnO2 under both the indoor and outdoor conditions, which is due to high solar spectrum absorption properties of SnO2 in the ultraviolet (UV) and near to far-infrared (IR) regions. The highest surface temperature of 101.61°C has been observed for specimens containing 15 wt% SnO2 in black paint under indoor conditions at 1000W/m2 irradiation levels, which is 53.67% higher compared to bare aluminum plate and 16.91% higher compared to only black paint coated aluminum plate. On the other hand, the maximum temperature of 74.96°C has been recorded for the identical specimens containing 15 wt% SnO2 under uncontrolled outdoor conditions. The recorded temperature is 47.96% higher than the bare aluminum plate and 14.88% higher than the black paint-coated aluminum plate. The difference of maximum temperatures under indoor and outdoor conditions is due to uncontrolled outdoor conditions and convective losses.

Magneto-convective nanofluid flow analysis in a square cavity driven by exothermic chemical reaction Science Direct, November, 2022 Publication Type: Journal View Summary/Abstract , Publication Link
We investigate the unsteady laminar convective magnetohydrodynamic nanofluids flow in a square cavity driven by an exothermic chemical reaction. Because exothermic chemical reactions are intrinsic in nanofluidic flow applications, we consider this exothermic chemical reaction in the analysis, which is governed by Arrhenius kinetics energy. A water-based nanofluid containing iron oxide (Fe3O4) nanoparticles is employed in the simulation. The square cavity is accurately propounded by a combination of suitable heating and flow conditions. The left vertical wall of the enclosure is considered a higher unevenly heated wall, the right vertical wall of the domain is considered a relatively cool constant temperature, and the upper and lower walls are considered insulating walls. Each wall assumes a no-slip condition. The nanofluid governing equations are transformed into the non-dimensional set of equations using similarity analysis and then modified into finite element equations. Galerkin's method in finite element analysis is used to obtain the results of the problem. The results show that the Rayleigh number, the Frank-Kamenetsky number, and the nanosolid volume ratio all have significant effects on the convective flow regime, and the average Nusselt number increases with these parameters. Due to the greater value of the Rayleigh number (Ra = 106), the average Nusselt number increased to 75.92%, and heat generation due to a strongly exothermic reaction (higher Frank-Kamenetskii number) can blow up the bounded solution. The water-Fe3O4 nanofluid achieves a greater rate of heat transfer (maximum 22.65%) than that of the base fluid.

Radiative effect on unsteady magneto-convective heat-mass transport by micropolar binary mixture passing a continuous permeable surface Hindawi, November, 2022 Publication Type: Journal View Summary/Abstract , Publication Link
Radiation is an important branch of thermal engineering which includes geophysical thermal insulation, ground water pollution, food processing, cooling of electronic components, oil recovery processes etc. An analysis of unsteady magneto-convective heat-mass transport by micropolar binary mixture of fluid passing a continuous permeable surface with thermal radiation effect has been introduced in this paper. The governing equations are transformed into coupled ordinary differential equations along with Boussinesq approximation by imposing the similarity analysis. Applying the shooting technique, the obtained non-linear coupled similarity equations are solved numerically with the help of “ODE45 MATLAB” software. The results of the numerical solutions to the problem involving velocity, temperature, concentration and micro-rotation are presented graphically for different dimensionless parameters and numbers encountered. With an increase of suction parameter, the velocity distributions very closed to the inclined permeable wall decrease slightly where . But for the uplifting values of sunction, both micro-rotation profile and species concentration enhance through the boundary layer. The skin-friction coefficient increases about 61%, 13%, 27% for rising values of Prandtl number (0.71-7), radiation effect (0 - 1) and thermal Grashof number (5-10), respectively, but an adverse effect is observed for magnetic field (1 - 4), inclined angle and Schmidt number (0.22 - 0.75). Heat transfer and mass transfer reduce about 82%, 53%, respectively, in increasing of Pr (0.71-1) and 36%, 11%, respectively, in increasing of thermal radiation (0 - 1). The surface couple stress increases about 26%, 49%, 64% and 30% with the increasing values of magnetic field (1-4), inclination angle , suction (0-1) and Schmidt number (0.22-0.75), respectively. Finally, the present study has been compared with the earlier published results. It is observed that the comparison bears a good agreement.

Numerical appraisal of time-dependent peristaltic duct flow using Casson fluid Science Direct, November, 2022 Publication Type: Journal View Summary/Abstract , Publication Link
Interruption of continuous process and decreasing flow rate over time are very common challenges in peristaltic flow. This research takes an initiative to restrain the thermal and fluid flow rate over time by unsteady finite element analysis of Casson fluid flow through a two-dimensional peristaltic duct. The time-dependent flow equation exists in conjugate forced convection and the energy equation consists of radiative heat flux and entropy reduction. The top and bottom walls of the peristaltic duct are considered as contact with air. A circular bolus is set up in the middle of the duct. Four types of Casson fluids like slurry, silicone oil, apple juice, and blood are used as working fluids. The finite element method of Galerkin's residual technique is applied to solve the leading second ordered non-linear partial differential equations with proper border conditions. The effects of pertinent parameters on entropy reduction and thermal transport are analyzed. Results are displayed qualitatively in terms of streamlines, vortex field, and heatline contours as well as quantitatively in the form of average temperature, mean thermal, viscous, and total entropy. The obtained numerical results show that thermal performance and entropy reduction are significantly influenced by forced convection, atmospheric characteristics, internal thermal radiation, and Casson fluids. Approximately 6.99% and 72.13% increment of temperature and flow irreversibility are found for shear stress variation of Casson fluid from thickening to thinning. Decreasing thermal performance of 18.71% and increasing energy loss of 38.07% are noticed within the variation of Casson fluids (slurry, silicone oil, apple juice, and blood). About 14.05% enhancement of thermal transport and 64.91% reduction of total entropy are observed due to increasing internal thermal radiation from 0.5 to 2. The numerical results from this research represent a better thermal and fluid flow rate over time compared to the experimental/existing methodology/numerical research. The obtained flow and thermal transport phenomena expose many attention-grabbing performances which deserve additional investigation on Casson fluid characteristics particularly the continuation of flow rate. A fine approach to the biological peristaltic system is offered by the results.

Thermal operation by nanofluids with various aspects: A comprehensive numerical appraisal Taylor & Francis , September, 2022 Publication Type: Journal View Summary/Abstract , Publication Link
This research is a good understanding of unsteady convective transport of nanofluids inside a skewed cavity considering MHD, different combinations of base fluids and nanoparticles, shapes, sizes (1–50 nm), volume fractions, and with/without Brownian effects. The right and left sidewalls of the enclosure are heated at low and high temperature, respectively, whereas the bottom and top walls are insulated. The finite element technique with Galerkin’s residual has been implemented for solving non-linear PDEs that govern the flow for the current problem. The numerical simulations have been presented using streamlines, isotherms, and temperature transport rates for different parameters, non-dimensional time, skewed angles, base fluids, nanoparticles, shapes, sizes, and volume fractions. The outcomes show that heat transport rate augments about 12.55% with an additional 2.5% nanoparticles into the base fluid for Cu-H2O nanofluid. An optimal thermal transport rate is observed for kerosene-based nanofluid, blade shape, and 1 nm size of nanoparticles. Magnetite nanoparticles show a greater thermal performance of 4.72% than higher thermal conductivity nanoparticles (copper and cobalt). Thermal transport enhances about 110.78% with Brownian motion for 5% concentrated blade-shaped kerosene-Fe3O4 nanofluid than without Brownian effects. In addition, a new linear regression equation with multiple variables has been derived from the obtained results.

Mathematical Study of a Resource-Based Diffusion Model with Gilpin–Ayala Growth and Harvesting Springer Nature, 15 September, 2022 Publication Type: Journal View Summary/Abstract , Publication Link
This paper focuses on a Gilpin–Ayala growth model with spatial diffusion and Neumann boundary condition to study single species population distribution. In our
heterogeneous model, we assume that the diffusive spread of population is proportional to the gradient of population per unit resource, rather than the population density
itself. We investigate global well-posedness of the mathematical model, determine
conditions on harvesting rate for which non-trivial equilibrium states exist and examine their global stability. We also determine conditions on harvesting that leads to
species extinction through global stability of the trivial solution. Additionally, for
time periodic growth, resource, capacity and harvesting functions, we prove existence
of time-periodic states with the same period. We also present numerical results on the
nature of nonzero equilibrium states and their dependence on resource and capacity
functions as well as on Gilpin–Ayala parameter θ. We conclude enhanced effects of
diffusion for small θ which in particular disallows existence of nontrivial states even
in some cases when intrinsic growth rate exceeds harvesting at some locations in space
for which a logistic model allows for a nonzero equilibrium density.

Dynamics of heterogeneous population due to spatially distributed parameters and an ideal free pair frontiers, 09 August , 2022 Publication Type: Journal View Summary/Abstract , Publication Link
Population movements are necessary to survive the individuals in many cases
and depend on available resources, good habitat, global warming, climate
change, supporting the environment, and many other issues. This study
explores the spatiotemporal effect on the dynamics of the reaction-diffusion
model for two interacting populations in a heterogeneous habitat. Both species
are assumed to compete for different fundamental resources, and the diffusion
strategies of both organisms follow the resource-based diffusion toward a
positive distribution function for a large variety of growth functions. Depending
on the values of spatially distributed interspecific competition coefficients, the
study is conducted for two cases: weak competition and strong competition,
which do not perform earlier in the existing literature. The stability of global
attractors is studied for different conditions of resource function and carrying
capacity. We investigated that in the case of weak competition, coexistence
is attainable, while strong competition leads to competitive exclusion. This is
an emphasis on how resource-based diffusion in the niche impacts selection.
When natural resources are in sharing, either competition or predator-prey
interaction leads to competitive exclusion or coexistence of competing
species. However, we concentrate on the situation in which the ideal free pair
is achieved without imposing any other additional conditions on the model’s
parameters. The effectiveness of the model is accomplished by numerical
computation for both one and two space dimension cases, which is very
important for biological consideration

A reaction-advection-diffusion model in spatial ecology: theoretical and computational analysis Khulna University Studies, 26 September, 2022 Publication Type: Journal View Summary/Abstract , Publication Link
In a confined heterogeneous habitat with two species interacting for common resources, the research analyzes a reaction-advection-diffusion type dispersal model with homogeneous Neumann
boundary conditions for generalized growth functions. Both species follow the same symmetric
growths law, but their dispersal strategies and advection rates are different. The following pattern
is used to consider the competition strategy: in a bounded heterogeneous habitat, the first population disperses according to its resource functions, whereas the second population disperses according to its carrying capacity. We investigate the model in two scenarios: when carrying capacity and
resource functions are non-proportional, competitive exclusion occurs, and one species drives the
other to extinction in the long run for various similar and unequal carrying capacities of competing
species. However, coexistence is achievable for different resource distribution consumption if the
resource distribution and the carrying capacity phase of the second species are non-constant and
similar. A series of numerical computations are used to demonstrate the model’s efficacy in oneand two-dimensional instances, which is particularly significant for environmental considera

Thermal performance of ternary-hybrid nanofluids through a convergent-divergent nozzle using distilled water - ethylene glycol mixtures Elsevier, 12 July, 2022 Publication Type: Journal View Summary/Abstract , Publication Link
A computational analysis is conducted based on ternary-nanoparticles performance for base fluid mixture
through a convergent-divergent (CD) nozzle. Since the thermal phenomena through a CD nozzle exposes many
attention-grabbing performances, it deserves additional investigation for laminar flow characteristics. Using
ternary-nanoparticles at different base fluid mixture makes the study more robust and interesting to analyze the
real situation better. In this study, the properties of cobalt (Co), silver (Ag), and zinc (Zn) nanoparticles along
with base fluid mixtures of distilled-water (DW) and ethylene glycol (EG) as (100:0), (60:40), (50:50), and
(0:100), are employed. A wide range of inlet velocity, solid concentrations, nanoparticle size and magnitude of
nanoparticle shape factor is considered in this research. The mixtures of nanoparticles are considered as a ratio of
(0:1/2:1/2), (1/2:0:1/2), (1/2:1/2:0), (1/6:1/6:2/3), (1/6:2/3:1/6), (2/3:1/6:1/6) and (1/3:1/3:1/3). The
mathematical model is formulated using Navier-Stokes equations, energy conservation with proper boundary
conditions, and solved using finite element method. Among the considered base fluid mixtures, the highest heat
transfer rate is obtained for EG-Co-Ag-Zn nanofluid. A relatively higher heat transfer rate is found for all base
fluid mixtures with nanoparticles ratio (1/6:2/3:1/6) compared to other combinations. Furthermore, advanced
rate of thermal transport is found using laminar shape nanoparticles.

Double-Diffusive Unsteady Flow in a Roof-Based Air Ventilation System with Variable Prandtl Number Springer Nature, Arabian Journal for Science and Engineering , 2022 Publication Type: Journal View Summary/Abstract , Publication Link
Double-diffusive mixed convection problem had been a notable topic of research in the last decade. Lack of study is noticed under mixed convection using this double-diffusive in an enclosure specifically for roof-based ventilation systems with unsteady, partially heated conditions. This study investigates the Prandtl number effect in a double-diffusive unsteady flow in a square-shaped room where the upper channel was used for ventilation, and inside the enclosure, the walls are partially heated and mass concentrated. Galerkin residual method was implemented to get the governing equations. The Prandtl number 0.071 ≤ Pr ≤ 7.1 was chosen for the study, changing the dimensionless time 0.1 ≤ τ ≤ 1. The results have been shown in the mode of graphical representation and contour plots to observe the Prandtl number effect in such problem. The velocity streamline, isotherm, isoconcentration plots, heat and mass transfer rate, average fluid temperature and average mass concentration, etc., are shown. Results showed that heat and mass transfer rise with the growth of the Prandtl number. This research would be the guide for the design consideration in such double-diffusive systems like roof-based air ventilation systems with partial heat and mass generation.

Heatline visualization in hydromagnetic natural convection flow inside a prismatic heat exchanger using nanofluid Elsevier, International Journal of Thermofluids, 2022 Publication Type: Journal View Summary/Abstract , Publication Link
This article deals with a numerical analysis of magneto hydrodynamic natural convection phenomena in a prismatic heat exchanger containing Cu-nanoparticles with water as a base fluid. The nature of this fluid flow is steady, and a heat exchanger is created by involving two uniform cylinders with the same shape in a prismatic cavity. To create the heat exchanger and the buoyancy force, a hot cylinder and another cool cylinder are taken a left and right sides respectively. All other walls of this prismatic cavity are kept as heat insulation. For solving governing equations, the finite element technique is applied by involving Galerkin weighted residual method. The impact of the magnetic field, the buoyancy force, and the size of nanoparticles are explained with the help of involving parameters Rayleigh number (Ra), Hartmann number (Ha), and the nanoparticles volume fraction (ϕ). These parameters are graphically and physically explained by using streamline, isotherm, and heatline contours. The Nusselt number is also calculated and explained in detail to show the validation of this investigation. The outcomes indicate that the natural convective heat and energy transfer are improved by increasing the Rayleigh number, and the nanoparticle volume fraction. Reverse behavior is noticed for the upsurge of Hartmann number. The findings of this heat exchanger model can be pragmatic to construct an operative cooling system for numerous shape mechanical chambers.

Thermal performance of a hollow cylinder with low conductive materials in a lid-driven square cavity with partially cooled vertical wall Elsevier, Thermal Science and Engineering Progress, 2022 Publication Type: Journal View Summary/Abstract , Publication Link
Extensive research has focused on mixed convection in a lid-driven cavity. However, the thermal characteristics of a hollow cylinder made of low-conducting materials such as wood, high-density plastic, bricks, and concrete are not explored, even though they have a lot of real-world applications in engineering and technology. Thus the thermal performance of a hollow cylinder with several low conductive materials such as wood, high-density plastic, bricks, and concrete is investigated in this study. A square enclosure with a moving lid and partially cooled right vertical wall is considered. A heated hollow cylinder is placed in the center of the enclosure as a heat source. A set of governing equations with the appropriate initial and boundary conditions of this model is solved using finite element approach based on Galerkin weighted residual method. The numerical study is performed by varying the thermal conductivity (K) of the cylinder’s materials with transient conditions, and outcomes are depicted in terms of streamlines, isotherms, and different thermo-hydrodynamic properties such as average shear rate, drag force, average rate of heat transfer and heat absorption rate. The results indicated that the heat transfer rate of wood is initially greatest at the top but gradually decreases to the rock-bottom. Furthermore, the heat absorption rate of all materials decreases significantly over time; on average, wood absorbs 31% more heat than concrete.

Effect of unsteady relative thermal and concentration boundary layer thickness on mixed convection in a partially heated contaminated enclosure Elsevier, South African Journal of Chemical Engineering, 2022 Publication Type: Journal View Summary/Abstract , Publication Link
Double diffusive flow under mixed convection has become a significant area of research. This study aims to evaluate the Lewis number effect in such a double-diffusive problem in a roof-based air-ventilated system. The Lewis number 0.01 ≤ Le ≤ 5 was chosen for the study, considering other parameters as constant to observe the impact of different heat and mass transfer properties varying the dimensionless time 0.1 ≤ τ ≤ 1. The Galerkin residual technique was chosen to generate the governing equations. The outcomes have been plotted in streamlines, isotherms, isoconcentration, heat and mass transfer, average fluid temperature and mass concentration. The major findings elucidate that heat and mass transfer rate augments when Lewis number goes higher and vice versa. Moreover, when the thermal diffusivity is higher than the mass diffusivity, the average fluid temperature and mass concentration become lower. Overall, this study will be a guide on double-diffusive system design, such as roof-based air ventilation systems.

This numerical study was conducted to investigate the ventilation and airflow in a confined enclosure undergoing rapid inclusion of heat and contaminants representing air quality changes in working environments. A flow of air is passing inside a square enclosure with a heat source and a pollutant source on the right and bottom wall, creating double-diffusion, as well as two ventilation ducts on the upper sides asserting mixed convection. The Galerkin weighted residual method is implemented, which is based on the finite element method. For fixed values of Lewis number, Le = 0.5, Richardson number, Ri = 1, Reynolds number, Re = 100, and Prandtl number, Pr = 1.01, simulations were done with Buoyancy Ratio, Br = −10, 1, 10 and 20 over dimensionless time, τ = 0.1, 0.5, and 1.0. The results have been shown with the streamline, isothermal lines, iso-concentration lines, average Nusselt and Sherwood number, average fluid temperature, average mass concentration, and the average temperature at the square cavity's exit port plots. The findings have been discussed to ensure understanding of the changes in parameters, and an enhancement in heat as well as mass transfer was seen with the rapid change in dimensionless time.

Periodic Unsteady Natural Convection on CNT Nano-powder Liquid in a Triangular Shaped Mechanical Chamber Elsevier, International Journal of Thermofluids, 2022 Publication Type: Journal View Summary/Abstract , Publication Link
Nanoparticle is highly used in enhancing thermal performance, especially in lid-driven cavity flow in powder-related applications. Many researchers considered different conditions, such as MHD, radiation, and mixed convection incorporating nano liquid in such flow. However, no study was carried out with CNT-water nano liquid in a triangular cavity, heated sinusoidally under natural convection to determine the Rayleigh number (Ra) and nano-powder liquid concentration effect on heat transfer. As a result, this study attempts to find the Rayleigh number and particle concentration effects in such transient cavity flow. The governing equations were employed with the Galerkin residual method. While calculating the thermal conductivity and dynamic viscosity of the nano liquid, Brownian motion was taken into consideration. The four solid volume fractions (0.01, 0.05, 0.1, 0.15) and the Ra (104 ≤ Ra ≤ 106) were chosen to evaluate the impact within dimensionless time (0.1 ≤ τ ≤ 1). The findings have been shown by plotting the streamlines, isotherms, heat transfer variation, and pressure gradient. It is found that when the Rayleigh number goes up, the velocity, vorticity, and pressure gradient magnitude become high. But, the fluid flow vortices decrease with dimensionless time. Due to the sinusoidal heat flux conditions, the variation of the result was found to be sinusoidal as well. When the nanoparticle concentration rises, the heat transfer rate and average fluid temperature also increase. Therefore, the highest heat transfer rate is found using the nano liquid with a15% concentration.

Extraction of some optical solutions to the (2+1)-dimensional Kundu–Mukherjee–Naskar equation by two efficient approaches Elsevier, Partial Differential Equations in Applied Mathematics, 2022 Publication Type: Journal View Summary/Abstract , Publication Link
The Kundu–Mukherjee–Naskar (KMN) model is considered for describing the pulse propagation in optical fibres and communication systems. Two efficient approaches via the exp
-expansion and the improved
-expansion schemes are applied to the KMN model and in order to convert the KMN equation to an ODE, we test the complex wave conversions and present some optical soliton solutions, which are expressed in terms of hyperbolic, rational and trigonometric functions. We create three dimensional and two-dimensional images to explain the underlying optical wave properties of the KMN equation and compare our solutions with the ones in the literature. Our example shows that the two adopted methods provide an efficient mathematical tool for constructing new optical wave solutions to nonlinear partial differential equations arising in fibre optic communication systems.

Radiation Effect on Unsteady MHD Mixed Convection of Kerosene Oil-Based CNT Nanofluid Using Finite Element Analysis Elsevier, Alexandria Engineering Journal, 2022 Publication Type: Journal View Summary/Abstract , Publication Link
This work conducts a numerical analysis of thermal radiation with a semicircular heater on the middle part of the bottom wall and a sliding lid on the top in a square enclosure. Magnetohydrodynamic (MHD) unsteady mixed convection for kerosene oil-based CNT nanofluid is studied. The finite element-based Galerkin residual technique is used to obtain nonlinear dimensionless governing equations. The thermal conductivity and dynamic viscosity models incorporate nanoparticle Brownian motion. Simulations were conducted for Reynolds number = 100, Hartmann number = 10, Richardson number = 1, and particle concentration = 0.05. The effects of fluid velocity magnitude, pressure gradient, temperature gradient magnitude, average temperature, bulk temperature, drag force of the sliding lid, and Nusselt number of the semicircular heater were investigated for different radiation parameters and dimensionless time. Results showed that increasing radiation intensity and dimensionless time improves fluid velocity, pressure gradient, and temperature gradient but decreases the heat transfer rate of the semicircular heater. Furthermore, the drag force of the moving lid is likewise found to be substantially dependent on the radiation parameter as well as dimensionless time. It is worth noted that after a while, the considered parameter exhibits consistent behavior.

Wave solutions of the couple Drinfel’d–Sokolov–Wilson equation: New wave solutions and free parameters effect Science Direct, Journal of Ocean Engineering and Science, 2022 Publication Type: Journal View Summary/Abstract , Publication Link
This manuscript employs an exact and explicit soliton solution of the Drinfel'd–Sokolov–Wilson (DSW) equation. The wave phenomena of the obtained solutions are applied to water wave mechanics, fluid dynamics, ocean engineering and science. The new auxiliary equation (NAE) method was not applied to the DSW model. As a result, we applied this model to construct a lot of analytic solutions in the expression of hyperbolic, trigonometric, and explicit functions that included free parameters. The obtained solutions are explained in some plots in three-dimensional (3D) and two-dimensional (2D) graphs in this paper, which also discusses the effect of the wave phenomena in 2D diagrams. However, we have made comparisons between our solution and other solutions in the previous literature. Therefore, it is revealed that the mentioned method may be a potential tool for creating new precise soliton solutions for various NLEEs, which play an important role in applied science and engineering.

Numerical study of low Reynolds number effect on MHD mixed convection using CNT-oil nanofluid with radiation Science Direct, Results in Engineering, 2022 Publication Type: Journal View Summary/Abstract , Publication Link
An enclosure with a moving lid is commonly used in heat and mass transmission. Also, many investigations have been done so far on a mixed convective flow in a cavity, but no research has been done to observe the low Reynolds number effect in the presence of MHD and radiation in a cavity with a semi-circular heater incorporated kerosine oil-based CNT nanofluid. In addition, oil-based nanofluid makes the working fluid more stable at a higher temperature. This study numerically investigates the time-dependent effect of low Reynolds number on Kerosene oil-based CNT nanofluid with magnetic field and radiation. The governing equations were employed with the finite element method based Galerkin residual technique. Brownian motion of nanoparticles was considered to determine the thermal conductivity and dynamic viscosity. Lower values of Reynolds number are taken, such as 50 to 200 with fixed values of radiation parameter, the particle concentration, the Hartmann number, and the Richardson number. The results were illustrated as heat transfer and fluid flow for three dimensionless time conditions. Results indicate that increasing the fluid velocity improves the Nusselt number and drag force. The vorticity rises to 54% while increasing the fluid velocity, however, the pressure gradient and average temperature become lower. It is also found that the average fluid velocity is 2.2 times higher in the Re = 50 than in the Re = 100. For the time dependency of this study, the thermo-hydrodynamics behavior changes with dimensionless time. Finally, this study would be a guide for designing thermal devices related to heat transfer, especially using the Kerosene oil-based CNT nanofluid under different conditions.

Unsteady periodic natural convection in a triangular enclosure heated sinusoidally from the bottom using CNT-water nanofluid Science Direct, Results in Engineering, 2022 Publication Type: Journal View Summary/Abstract , Publication Link
This research examines the natural convection phenomena in a triangular enclosure, assumed as a mechanical chamber. Water-based CNT-nanofluid was used as the fluid. The nature of the flow is unsteady, and a sinusoidal heat source is situated at the bottom of the triangle. The inclined two walls of the triangle are assumed as cold temperature. Based on the finite element method, dimensionless nonlinear governing equations were obtained employing the Galerkin weighted residual method. Brownian motion of nanoparticles was considered to determine the thermal conductivity and dynamic viscosity. Rayleigh number (Ra), oscillation period τp, and dimensionless time τ are assumed as primary controlling factors, and nanofluid concentration is considered as constant φ = 0.04. The result indicates that the heat transfer rate displays varied patterns varying the Rayleigh number, and it rises as the oscillation period increases. The fluid temperature and flow fields exhibit periodic behavior due to the sinusoidal heat source. The findings of this work can be utilized to build an effective cooling or heating system for the mechanical chamber, ensuring that temperature distributions are effective and consistent.

Thermophysical properties of Kerosene oil-based CNT nanofluid on unsteady mixed convection with MHD and radiative heat flux Science Direct, Engineering Science and Technology, an International Journal, 2022 Publication Type: Journal View Summary/Abstract , Publication Link
Oil-based nanofluids are used to strengthen the stability of nanofluids as well as their thermophysical properties when they are exposed to high temperatures. The time-dependent thermophysical characteristics of multiwalet carbon nanotubes for kerosine oil-based nanofluid are numerically explored in this study. Considering a constant magnetic field, the radiative domain is examined in a lid-driven squared shape cavity with a semicircular heater on the middle part of the bottom wall. The Galerkin residual technique based on finite elements is used to obtain nonlinear dimensionless governing equations. Thermal conductivity along with dynamic viscosity models integrate Brownian motion of nanoparticles. The Reynolds number, the Hartmann number, the Radiation Parameter and the Richardson number are assumed to be constant to account for the fluctuation in solid volume fraction (ϕ = 0% to 10%). The results demonstrated that particle concentration improves the nanofluid’s thermophysical properties from 1 to 9 times than the 0% concentration and the heat transfer rate from 1 to 3 times. In addition, dimensionless time enhances all except the heat transfer rate and drag force of the sliding lid. It is worth noting that the considered parameter exhibits consistent behavior after a while.

Mixed convection heat transfer in a lid-driven enclosure with a double-pipe heat exchanger Science Direct, International Journal of Thermofluids, 2022 Publication Type: Journal View Summary/Abstract , Publication Link
The numerical investigation of mixed convection in a heat exchanger with double-pipe, where the upper lid is given a constant velocity, is presented in this paper. The governing equations, as well as the boundary conditions, define the physical problem. The boundary conditions and governing equations are translated into non-dimensional form and solved by means of a finite-element methodology based on the Galerkin weighted residual. The investigation is conducted for three different governing parameters; namely, Prandtl number (Pr), Richardson number (Ri) and Reynolds number (Re). The outcomes are presented in terms of streamlines, isotherms and average heat transfer rate. Computations are done for a range of Ri (0.01 ≤ Ri ≤ 10), Re (50 ≤ Re ≤ 500), and Pr (1 ≤ Pr ≤ 10) for different dimensionless time (τ = 0.1, 0.5, 1). It is found that the influence of Ri on streamlines, isothermal lines, and heat transfer rate is significant and the maximum heat transfer is gained when values of Ri and Re are higher and Pr is lower. It is also found that the flow strength increases substantially with time and multiple vortices emerge as the convection rate increases.

Numerical Analysis of Thermofluids inside a Porous Enclosure with Partially Heated Wall Science Direct, International Journal of Thermofluids, 2021 Publication Type: Journal View Summary/Abstract , Publication Link
In this study, heat transfer in a tall, rectangular permeable cavity with active thermal walls is investigated. Inside the enclosure, the two side walls' central portions are partially cooled at a fixed temperature. The central portion of the footwall is heated. Additionally, the top wall, the remaining portion of the footwall, and the side walls are insulated. The controlling equations are obtained from the Brinkman–Forchheimer-extended Darcy prototypical model using Boussinesq calculations. The leading equations are explained numerically by the finite element Galerkin method of weighted residuals. The computations are executed for some governing and physical parameters. The isotherms, streamlines and average heat transfer rate along with the partially active hot wall are shown for different groupings of governing parameters with respect to dimensionless time (τ). The outcomes indicated that the stream and thermal fields are strongly dependent on the considered parameters. It is also established that the average heat transfer rate is a function of these governing parameters.

IVESR Rumor Spreading Model in Homogeneous Network with Hesitating and Forgetting Mechanisms ACM, Journal of Applied Mathematics and Computation, 5(2), 105-118. DOI: 10.26855/jamc.2021.06.005, 2021 Publication Type: Journal View Summary/Abstract , Publication Link
In this paper, we study a new IVESR rumor spreading model with hesitating and forgetting mechanisms in homogeneous network. The rumor free and rumor prevailing equilibriums, and the basic reproduction number are calculated from the mean-field equations of the model. The local and global stability of rumor free equilibrium are proved by using Lyapunov function and LaSalle invariance principle, and the existence of rumor prevailing equilibrium is shown. In numerical simulations, it is found that the vaccination, prohibiting people to spread the rumor, can lessen the propagation of rumor in the network. We also show that the fuzziness of the rumor has a great impact on the size of spreader and the forgetting factor has a great effect on the rumor prevailing duration. Furthermore, we analyze the sensitivity of different parameters on and discussed how they affect the spreading and controlling of the rumor.

Temperature dissipation in a proficient mode has turned into a crucial challenge in industrial sectors because of worldwide energy crisis. In heat transfer analysis, shell and tube thermal exchangers is one of the mostly used strategies to control competent heat transfer in industrial progression applications. In this research, a numerical analysis of turbulent flow has been conceded in a shell and tube thermal exchanger using Kays-Crawford model to investigate the thermal performance of pure water and different concentrated water-MWCNT nanofluid. By means of finite element method the Reynold-Averaged Navier-Stokes (RANS) and heat transport equations along with suitable edge conditions have been worked out numerically. The implications of velocity, solid concentration, and temperature of water-MWCNT nanofluid on the fluid flow formation and heat transfer scheme have been inspected thoroughly. The numerical results indicate that the variation of nanoparticles solid volume fraction, inflow fluid velocity and inlet temperature mannerism considerably revolutionize in the flow and thermal completions. It is perceived that using 3% concentrated water-MWCNT nanofluid, higher rate of heat transfer 12.24% is achieved compared that of water and therefore to enhance the efficiency of this heat exchanger. Furthermore, a new correlation has been developed among obtained values of thermal diffusion rate, Reynolds number and volume concentration of nanoparticle and found very good correlation coefficient among the values.

Influence of Fin Length on Magneto-Combined Convection Heat Transfer Performance in a Lid-Driven Wavy Cavity MDPI, 31 August , 2021 Publication Type: Journal View Summary/Abstract , Publication Link
In the existent study, combined magneto-convection heat exchange in a driven enclosure having vertical fin was analyzed numerically. The finite element system-based GWR procedure was utilized to determine the flow model’s governing equations. A parametric inquiry was executed to review the influence of Richardson and Hartmann numbers on flow shape and heat removal features inside a frame. The problem’s resulting numerical outcomes were demonstrated graphically in terms of isotherms, streamlines, velocity sketches, local Nusselt number, global Nusselt number, and global fluid temperature. It was found that the varying lengths of the fin surface have a substantial impact on flow building and heat line sketch. Further, it was also noticed that a relatively fin length is needed to increase the heat exchange rate on the right cool wall at a high Richardson number. The fin can significantly enhance heat removal performance rate from an enclosure to adjacent fluid.

Study of mixed convection flow of power-law fluids in a skewed lid-driven cavity Wiley, May, 2021 Publication Type: Journal View Summary/Abstract , Publication Link
This study conducts a numerical simulation of mixed (combined) convective non-Newtonian fluid flow inside a two-dimensional cavity (skewed) having a moving lid. The upper and bottom extremities of the cavity with different temperatures and two insulated side walls cause natural convection. Moreover, the forced convection is maintained by the motion of the lid with constant velocity. The governing equations are nondimensionalized with appropriate transformations and then transformed into curvilinear coordinates. A finite volume numerical procedure with a collocated grid arrangement is used to solve these equations. Comparisons with previously reported results are carried out, which shows an excellent agreement. Non-Newtonian behaviors such as pseudo-plastic (shear-thinning) and dilatant (shear-thickening) are considered using the power-law model, and thus the power-law index is chosen accordingly. A wide range of the governing dimensionless parameters which affect the mixed convection flow inside the skewed cavity, including Grashof number (), Richardson number (), Reynolds number ( = 100 and 400), and power-law index (). The Prandtl number ( = 10) is fixed and the skew angles (, and ) are considered for acute, right-angle, and obtuse angles. The obtained numerical outcomes of the study are shown graphically and also in tabular form for vertical and horizontal velocities, streamlines, isotherms, temperature distributions, and the rate of heat transfer and insight physics of the flow features, are discussed thereafter. It can be concluded that the rate of heat transfer in the present case is sensitive to the skew-angle as well as power-law index, and the maximum heat transfer occurs in the case of dilatant (shear-thickening) fluid.

Numerical modeling of Buongiorno’s nanofluid on free convection: Thermophoresis and Brownian effects BanglaJOL, Journal of Naval Architecture and Marine Engineering, 2021 Publication Type: Journal View Summary/Abstract , Publication Link
In this research, numerical modeling is conducted on free convective flow inside a trapezoidal domain with sinusoidal material and temperature allocations at both inclined boundaries using Buongiorno’s nanofluid. The model considers thermophoresis with Brownian activity effects taking place in the flow, temperature as well as concentration contours. Non-uniform nanoparticle solid concentration and temperature allocations have been imposed at both inclined surfaces. Top and bottom parallel surfaces have been kept as adiabatic. All the walls have been considered as no-slip and impermeable. The leading equations in addition border conditions are initially converted into a dimensionless pattern by a suitable similarity transformation and then resolved arithmetically employing the finite element technique with Galerkin’s residual. Buongiorno’s model of nanofluid on thermal and material transports, and flow structure has been investigated in detail. Outcomes have been displayed in the form of velocity, temperature, and concentration contours with various governing factors like Brownian action, Lewis number, Buoyancy relation, thermophoresis, Rayleigh number, Prandtl number, etc. Also, the rate of thermal transport has been calculated. The thermophoresis and Brownian effects on velocity, heat, and material fields are identified and finally, the flow, heat, and concentration controlling parameters for a specific material and thermal transport applications inside a trapezium-shaped cavity are obtained. Result demonstrates that the increase of Brownian action guides to enhance thermal transport by 34.75 and 34.27% for the right and left walls, respectively.

Oriented magneto-conjugate heat transfer and entropy generation in an inclined domain having wavy partition World Scientific, International Communications in Heat and Mass Transfer, 2021 Publication Type: Journal View Summary/Abstract , Publication Link
Energy transmission in an efficient mode has become a crucial challenge in both industrial and biomedical systems because of the worldwide energy crisis. An initiative has been taken by the present research for designing energy-efficient industrial and biomedical systems using different fluids. This numerical study focuses on investigating magneto-hydrodynamic conjugate natural convection and entropy generation of a hybrid nanofluid (Ag-MgO-water) in a differentially heated square domain including heat-generating sinusoidal solid partition. The partition is mid-positioned with a finite thickness and divides the computational regime into two flow domains. The FEM has been applied for solving the governing PDEs. The effects of magnetic field intensity and orientation, cavity inclination, heat generation from the partition and volume fraction of hybrid nanoparticles on temperature distribution, flow field and local entropy generation have been investigated and displayed by isotherms, streamlines and isentropic lines, respectively. The contours have been plotted at the highest Rayleigh number for better visualization of thermo-fluid interaction. Considering a wide variation of free convection, thermal performance is determined through the computation of the average Nusselt number along the hot wall and system energy loss has been evaluated through the calculation of average total entropy generation as well as average Bejan number in both fluid zones. The obtained numerical results show that thermal performance and entropy generation are significantly influenced by the magnetic field intensity and cavity inclination. Thermo-fluid energy transfer is reduced by 11.62% for the highest magnetic field strength whereas the increase of cavity tilting is responsible for a 56.72% decrease in thermal performance. A new regression equation has been derived from the obtained results. The numerical study carried out in this research has superior results compared to the existing methodology and/or experimental/ numerical research.

Analysis of boundary layer nanofluid flow over a stretching permeable wedge-shaped surface with magnetic effect BanglaJOL, Journal of Naval Architecture and Marine Engineering, 2021 Publication Type: Journal View Summary/Abstract , Publication Link
The problem of steady two-dimensional boundary layer flow of momentum, heat and mass transfer over a stretching permeable wedge-shaped surface in a nanofluid in presence of magnetic field has been studied. In this respect, the governing partial differential equations have been converted into ordinary differential equations by using the local similarity transformation. The transformed governing equations have been then solved numerically using the bvp4c in MATLAB software. The effects of the pertinent parameters, namely wedge angle parameter (β), Brownian motion (Nb), thermophoresis (Nt), magnetic parameter (M), moving wedge parameter (λ), permeability parameter (K*), Prandtl number (Pr), and Lewis number (Le) on fluid velocity, thermal and concentration within the boundary layer have been analyzed. The numerical results obtained of the skin friction coefficients, local Nusselt number and local Sherwood number, as well as the velocity, temperature and concentration profiles have been presented graphically and also in tabular form. The results indicate that the momentum boundary layer thickness increases with increasing values of wedge angle and moving wedge but reduces for magnetic and permeability effects. The heat transfer rate increases for wedge angle, moving wedge, Brownian motion but decreases for thermoporesis and magnetic effects. The mass transfer rate decreases for Brownian motion and thermoporesis effects but increases for wedge angle and moving wedge parameters. Finally, the numerical results have been compared with previously published research and found to be in good agreement.

Numerical analysis of photovoltaic power generation in different locations of Bangladesh Shahid Rajaee Teacher Training University (SRTTU), Journal of Computational and Applied Research in Mechanical Engineering, 2021 Publication Type: Journal View Summary/Abstract , Publication Link
Photovoltaic (PV) module is one of the most useful, sustainable and non-harmful products in the field of renewable energy. It offers longer service period for least maintenance cost. The elements of PV are abrasive, easy for designing, and their structure like the stand-alone technique gives production from micro to mega-power level. A 3D numerical system of PV module has been built up and solved applying FEM technique-based software COMSOL Multiphysics in this article. The average solar irradiation and optimum tilt angle for six divisions (Dhaka, Chittagong, Rajshahi, Khulna, Barishal and Sylhet) in Bangladesh have been calculated. The effects of solar radiation, angle of inclination, ambient temperature, and partial shading on temperature of solar cell, electrical power and PV module's electrical efficiency have been investigated. It has been observed from the results that the greatest value of electrical power 15.14 W is found in Rajshahi for solar radiation 209 W/m2. The highest electrical efficiency is found as 12.85% in Sylhet at irradiation level of 189 W/m2. For every 1° increase of inclination angle, electrical power and electrical efficiency level devalue by 0.06 W and 0.05%, respectively. Results also show that the efficiency level decreases from 14.66 to 11.32% due to partial shading area from 0 to 40%. PV module's electrical power; and electrical efficiency reduces approximately 0.01 W and 0.01%, respectively due to every 1°C addition of solar cell temperature.

Performance analysis of hybrid/single nanofluids on augmentation of heat transport in lid-driven undulated cavity Wiley, 24 June, 2020 Publication Type: Journal View Summary/Abstract , Publication Link
This numerical study reveals the heat transfer performance of hybrid/single nanofluids inside a lid-driven sinusoidal trapezoidal-shaped enclosure. The right and left inclined surfaces of the trapezium have been considered as insulated, whereas the bottom sinusoidal wavy and the flat top surfaces of the enclosure as hot and cold, respectively. The governing partial differential equations of fluid's velocity and temperature have been resolved by applying the finite element method. The implications of Prandtl number (4.2-6.2), Richardson number (0.1-10.0), undulation number (0-3), nanoparticles volume fraction (0%-3%), and nanofluid/base fluid (water, water–copper (Cu), water–Cu–carbon nanotube, water–Cu–copper oxide (CuO), water–Cu–TiO2, and water–Cu–Al2O3) on the velocity and temperature profiles have been studied. Simulated findings have been represented by means of streamlines, isothermal lines, and average Nusselt number of above-mentioned hybrid nanofluids for varying the governing parameters. The comparison of heat transfer rates using hybrid nanofluids and pure water has been also shown. The heat transfer rate is increased about 15% for varying Richardson number from 0.1 to 10.0. Blending of two nanoparticles suspension in base fluid has a higher heat transfer rate—approximately 5% than a mononanoparticle. Moreover, a higher average Nusselt number is obtained by 14.7% using the wavy surface than the flat surface of the enclosure. Thus, this study showed that applying hybrid nanofluid may be beneficial to obtain expected thermal performance.

Blood Flow Analysis Inside A Stenotic Artery Using Power-Law Fluid Model Crimson Publishers, 03 April, 2020 Publication Type: Journal View Summary/Abstract , Publication Link
This paper is devoted to study numerically a recent development of a non-Newtonian blood flow model
for a stenosed artery in human blood vessel. For numerical investigation the blood flow modeling
method of this research begins with non-Newtonian power-law model. The governing system of equation
based on incompressible Navier-Stokes equations with externally imposed magnetic resonance has
been generalized to take into account the mechanical properties of blood. The intent of this research
is to examine the effects of inlet velocity and imposed magnetic field on the blood flow throughout the
artery. The Galerkin’s weighted residual method of finite element system has been employed to resolve
the governing system of equation with proper boundary conditions. The numerical simulation has been
conducted for various inlet velocities from 0.005 to 0.1m/s and magnetic field strength from 0 to 6
tesla with superior convergence of the iterative structure. Results have been shown in terms of velocity,
surface plot of velocity, pressure and viscosity contours. Cross-sectional plots of velocity and viscosity
magnitudes across the stenotic contraction have also been displayed graphically. Obtained results of the
blood flow simulations indicate that viscosity increases due to increasing values of inlet velocity of blood
and magnetic strength.

A numerical analysis has been investigated for unsteady natural convection heat transfer problem in diamond shaped cavity. Carbon nanotube (CNT)-water nanofluid is used to analyze the heat transfer and compared with the pure water as working fluid. The lower right wall is kept at heated surface with constant heat flux and upper left wall is kept cold. Both the bottom left and upper right wall are kept adiabatic. The considered physical problem is characterized mathematically by a set of governing equations along with the corresponding boundary conditions. Galerkin weighted residual method of finite element analysis is used to solve the governing equations. Calculations are done for pertinent parameters such as the solid volume fraction (ϕ = 0.0–0.12) and Rayleigh number (Ra = 104–108) at dimensionless times (τ = 0.01 and 1.0) and fixed Pr = 6.2. Obtained results are presented in terms of average Nusselt number and maximum fluid temperature, streamlines and isotherms in graphs, charts and related contours. It has been observed that increase of Rayleigh number and solid volume fraction enhance the heat transfer rate and reduce the maximum fluid temperature. In this investigation the highest amount of overall heat transfer reaches up to 115%.

Effect of Joule Parameter on Mhd Mixed Convection in An Open Channel with Semi-Circular Heater on The Bottom Wall arpnjournals.org, ARPN Journal of Engineering and Applied Sciences, 2020 Publication Type: Journal View Summary/Abstract , Publication Link
A computational study has been done to investigate the heat and fluid flow in an open channel with a semicircular heater on the bottom wall under the effect of magnetic field. The walls of the channel are adiabatic while the semicircular heater in the bottom wall is kept at a constant temperature. The inlet and outlet are fixed at the left and right side of
the channel. The governing equations are solved by using Galerkin weighted residual finite element technique. In this
investigation the involved parameters are Reynolds number, Prandtl number, Hartmann number and joule heating
parameter. The effect of Reynolds number, Prandtl number and joule heating parameter for different Rayleigh numbers are
investigated while the magnetic parameter Ha (Hartmann number) is kept fixed at 10. The results show that at higher
Rayleigh number, joule effect parameter can be utilized to control heat and fluid flow fields. In addition, the effect of
Reynolds number on the heat and flow fields becomes insignificant at higher values of Rayleigh number. Finally, Prandtl
number is found to have a positive effect on heat transfer rate.

Numerical Investigation of Natural Convection in a Porous Enclosure with a Flush Mounted Heater on the Bottom Wall arpnjournals.org, ARPN Journal of Engineering and Applied Sciences, 2019 Publication Type: Journal View Summary/Abstract , Publication Link
In the present study, natural convection flows in a porous enclosure with a heater on the bottom wall have been
investigated numerically. To change the heat transfer in the cavity, a heater is placed at different locations on the bottom
wall of the cavity, while the top wall is considered to be cold and the vertical walls are kept adiabatic. The governing
equations are obtained by applying the Brinkman extended Darcy flow Model and Boussinesq approximation to
characterize heat flow paths along with the heat transfer rate. Finite element method is used to solve the dimensionless
governing equations with the specified boundary conditions. The parameters leading the problem are the Rayleigh number
(Ra), Darcy number (Da), Thermal conductivity ratio of porous media (k), Prandlt number (Pr), length and location of the
heater. To observe the effects of the heater locations at various length of heater on natural convection in the cavity, three
different locations of heater at bottom wall for various heater length with different values of Ra varying in the range 104
to 106 are considered. Simulated results are presented in terms of streamlines, isotherms and average Nusselt number at the hot wall in the cavity for the mentioned parameters. The results show that the length, locations of the heater and Rayleigh number have significant effect on the flow and thermal fields as well as the rate of heat transfer from the heated wall.

Computational study of natural convection in a rectangular porous enclosure with partially active wall in different heater and cooler positions mathsjournal, International Journal of Statistics and Applied Mathematics , 2019 Publication Type: Journal View Summary/Abstract , Publication Link
Natural convection heat transfer and fluid flow through a two-dimensional rectangular porous enclosure
with partially active thermal walls are investigated numerically in this study. A small part of two
sidewalls are partially cooled at a constant temperature θc and a small part of the bottom wall is kept at
constant temperature θh (θh > θc), where the top and the remaining part of the bottom wall and the side
walls of the enclosure are assumed to be insulated. The physical problems are presented mathematically
by different sets of governing equations (such as the mass, momentum and energy balance equations)
along with the corresponding initial and boundary conditions by using Brinkman-Forchheimer-extended
Darcy flow model and the Boussinesq approximation. Galerkin weighted residual method of finite
element analysis is implemented to discretise the governing equations. The analysis has been carried out
for the cavity Aspect ratio (Ar = 1, 2, 3), the three positions of heating source: left position (Lp), middle
position (Mp), right position (Rp) and the three positions of cooling source: top cold (Tc), middle cold
(Mc), and bottom cold (Bc) with various heater length and fixed Darcy number (Da), Porosity (ε), Prandtl
number (Pr) for two values of Grashof number (Gr = 105
, 106
) with respect to time (τ). Results are
presented in terms of isotherms, streamlines, average Nusselt number along the partially active thermal
wall for different combinations of the governing parameters. The results indicate that both the flow and
the thermal fields strongly depend on the above-mentioned parameters. The computational results also
indicate that the average Nusselt number at the heated part of active wall with respect to time are
depending on the aforementioned parameters. The results in terms of average Nusselt number are also

Heat transfer augmentation in an inclined lid-driven triangular enclosure utilizing nanofluids in forced convection flows tci-thaijo.org, Science & Technology Asia, 2019 Publication Type: Journal View Summary/Abstract , Publication Link
Heat transfer enhancement in a two-dimensional inclined lid-driven triangular enclosure utilizing cu-water nanofluids is investigated for various relevant parameters. A model is developed to analyze heat transfer performance of nanofluids inside an enclosure taking into account the force convection parameter, namely Reynolds number, Re. The transport equations are solved numerically using the Galerkin finite element method. Comparisons with previously published work on the basis of special cases are performed and found to be in excellent agreement. Results are obtained for a wide range of parameters such as the Richardson number, Ri, and Reynolds number, Re. Copper-water nanofluids are used with Prandtl number, Pr = 6.2 and Reynolds number, Re is varied from 100 to 500. The streamlines, isotherm plots and the variation of the average Nusselt number at the hot surface as well as average fluid temperature in the enclosure are offered and discussed in detailed. It is observed that the force convection parameter strongly influenced the fluid flow and heat transfer in the enclosure at the considered three convective regimes. Furthermore, the variation of the average Nusselt number at the heated surface is found to increase when Re increases and average fluid temperature in the cavity decreases with the raise of Re.

Ferrofluid convective heat transfer in a square cavity with sinusoidal temperature boundary condition at
the bottom wall under the influence of magneto hydrodynamics effect was investigated numerically in
the present study. Top wall is maintained at comparatively low temperature and Vertical walls are
assumed to be adiabatic. The working fluid is Fe3O4-water nanofluid. Single phase model is used to
estimate the behavior of ferrofluid and the Maxwell-Garnet model is used for modeling the effective

) with respect to dimensionless time (τ = 0.1, 1.0). The results are presented both in
terms of streamlines, isotherms and Local Nusselt number through the active thermal wall for different
combinations of the governing parameters. The results indicate that both the flow and the thermal fields
strongly depend on the above-mentioned parameters. The computational results also indicate that the
Local Nusselt number at the heated wall for different time are depending on the aforementioned

Mixed convective hybrid nanofluid flow in lid-driven undulated cavity: effect of MHD and Joule heating BanglaJOL, 31 December, 2019 Publication Type: Journal View Summary/Abstract , Publication Link
A numerical analysis has been conducted to show the effects of magnetohydrodynamic (MHD) and Joule heating on heat transfer phenomenon in a lid driven triangular cavity. The heat transfer fluid (HTF) has been considered as water based hybrid nanofluid composed of equal quantities of Cu and TiO2 nanoparticles. The bottom wall of the cavity is undulated in sinusoidal pattern and cooled isothermally. The left vertical wall of the cavity is heated while the inclined side is insulated. The two dimensional governing partial differential equations of heat transfer and fluid flow with appropriate boundary conditions have been solved by using Galerkin's finite element method built in COMSOL Multyphysics. The effects of Hartmann number, Joule heating, number of undulation and Richardson number on the flow structure and heat transfer characteristics have been studied in details. The values of Prandtl number and solid volume fraction of hybrid nanoparticles have been considered as fixed. Also, the code validation has been shown. The numerical results have been presented in terms of streamlines, isotherms and average Nusselt number of the hybrid nanofluid for different values of governing parameters. The comparison of heat transfer rate by using hybrid nanofluid, Cu-water nanofluid, TiO2 -water nanofluid and clear water has been also shown. Increasing wave number from 0 to 3 enhances the heat transfer rate by 16.89%. The enhanced rate of mean Nusselt number for hybrid nanofluid is found as 4.11% compared to base fluid.

Bingham Fluid Flow Simulation in a Lid-Driven Skewed Cavity using the Finite Volume Method Taylor & Francis , April, 2019 Publication Type: Journal View Summary/Abstract , Publication Link
In this paper, laminar flow of non-Newtonian (Bingham) fluid is studied numerically in a two-dimensional lid-driven skewed cavity that incorporates Papanastasiou exponential regularization approach of Bingham constitutive model [Papanastasiou, Flows of materials with yield, J. Rheol. 31 (1987), pp. 385–404]. Numerical simulation has been done using the finite-volume method with collocated grid arrangement. The governing equations including continuity and momentum are initially non-dimensionalized using appropriate transformation. To simulate irregular shape cavity flow problem, body-fitted non-orthogonal grids are used, and governing equations have been transformed to generalized curvilinear co-ordinates. In this study, two dimensionless parameters namely, Reynolds number and Bingham number are considered. A wide range of skew angles are considered which comprises both acute and obtuse angles. The obtained results are presented in terms of velocity and streamlines with yielded/unyielded region for different values of Bingham number and Reynolds number having different angles of the skewed cavity. The present results may be serve as benchmark results for comparison purpose in the case of non-Newtonian (Bingham) fluid flow.

Numerical and experimental investigation of the effect of operating conditions on performance of PVT and PVT-PCM Elsevier, Renewable Energy, 2019 Publication Type: Journal View Summary/Abstract , Publication Link
Irradiations incident on the photovoltaic module are converted only 15–20% into electrical energy and remaining are transformed into heat and drop electrical efficiency. Therefore, to harness both the thermal and electrical energy, hybrid photovoltaic thermal system is an optimum option. Moreover, phase change materials add more advantages of PV cell cooling and heat storage. A novel thermal collector has been designed as PVT and PVT-PCM systems to improve the heat transfer and performance. The 3D numerical analysis is done with COMSOL Multiphysics® software, and is validated at different volume flow rates of 0.5LPM to 3LPM, by experimental investigation at conditions of keeping the inlet water and ambient temperature at 27 °C and solar irradiation at 1000 W/m2. The experiment is carried out in indoor weather under controlled operating parameters and conditions with passive cooling of the module. Maximum 12.4% and 12.28% electrical efficiency of PVT is achieved numerically and experimentally respectively. Similarly, 12.75 and 12.59% electrical efficiency for PVT-PCM is obtained for experimental and numerical cases respectively. For PVT system, 10.13 and 9.2% electrical performance is improved. For PVT-PCM the electrical performance improvement is obtained as 12.91 & 12.75% numerically and experimentally respectively.

Effect of nanofluids on heat transfer and cooling system of the photovoltaic/thermal performance Elsevier, International Journal of Numerical Methods for Heat Transfer and Fluid Flow, 2019 Publication Type: Journal View Summary/Abstract , Publication Link
In this research, a 3D numerical model of PVT with a new baffle-based thermal collector system has been developed and solved using FEM. Water-based different nanofluids (Ag, Cu, Al), various solid volume fractions up to 3%, and variations of inlet temperature (20-40°C) have been applied. The numerical results show that increasing solid volume fraction increases the thermal performance of PVT systems operated by nanofluids, and optimum solid concentration is 2%. The thermal efficiency is enhanced approximately by 7.49, 7.08, and 4.97% for PVT systems operated by water-Ag, water-Cu, and water-Al nanofluids, respectively, compared to water. The extracted thermal energy from the PVT system decreases by 53.13, 52.69, 42.37, and 38.99 W for water, water-Al, water-Cu, and water-Ag nanofluids, respectively, due to each 1°C increase in inlet temperature. The heat transfer rate from the heat exchanger to cooling fluid enhances by about 18.43, 27.45, and 31.37% for the PVT system operated by water-Al, water-Cu, water-Ag, respectively, compared to water.

Energy and exergy analysis of the PVT system: Effect of nanofluid flow rate Elsevier, Solar Energy, 2018 Publication Type: Journal View Summary/Abstract , Publication Link
Solar energy is one of the promising resources to fulfil the energy demands to some level in place of fossil fuels to avoid environmental pollution. The efficiency of solar technology, e.g. photovoltaic panels, thermal systems or a combination of both technologies as photovoltaic thermal is a concern to increase at an optimum level. A three-dimensional numerical analysis of PVT systems using water and MWCNT-water nanofluid has been completed with FEM based software COMSOL Multiphysics®. A numerical investigation has been validated by the indoor experimental research at different mass flow rates of 30 to 120 L/h while keeping solar irradiation fixed at 1000 W/m2, inlet fluid and ambient temperature at 32 and 25 °C, respectively. Percent improvement of electrical efficiency of PV with nanofluid cooling at flow rate 120 L/h is obtained about 10.72 and 12.25% of numerical and experimental cases respectively. Optimization of the nanofluid for weight concentration is achieved at 0.75% MWCNT-water. Solar cell temperature reduces about 0.72 °C experimentally and 0.77 °C numerically per 10 L/h flow rate increment. Approximately 7.74 and 6.89 W thermal energy is enhanced per 10 L/h flow rate increment in numerical and experimental studies respectively. Percentage increment of thermal efficiency is found as 5.62% numerically and 5.13% experimentally for PVT system operated by water/MWCNT nanofluid with compared to water.

Water/MWCNT nanofluid based cooling system of PVT: Experimental and numerical research Elsevier, Renewable Energy, 2018 Publication Type: Journal View Summary/Abstract , Publication Link
In this research, an indoor experiment has been carried out of a PV module under controlled operating conditions and parameters. A novel design of thermal collector has been introduced, a complete PVT system assembled and water/MWCNT nanofluid used to enhance the thermal performance of PVT. An active cooling for PVT system has been maintained by using a centrifugal pump and a radiator have been used in the cycle to dissipate the heat of nanofluid in the environment to maintain proposed inlet temperature. 3D numerical simulation has been conducted with FEM based software COMSOL Multiphysics and validated by an indoor experimental research at different irradiation level from 200 to 1000 W/m2, weight fraction from 0 to 1% while keeping mass flow rate 0.5 L/min and inlet temperature 32 °C. The numerical results show a positive response to the experimental measurements. In experimental case, percentage of enhanced PV performance is found as 9.2% by using water cooling system. Higher thermal performance is obtained as approximately 4 and 3.67% in numerical and experimental studies, respectively by using nanofluid than water. In the PVT system operated by nanofluid at 1000 W/m2 irradiation, the numerical and experimental overall efficiency are found to be 89.2 and 87.65% respectively.

Effect of high irradiation and cooling on power-energy and performance of PVT system Elsevier, Renewable Energy, 2018 Publication Type: Journal View Summary/Abstract , Publication Link
Irradiation level is the key factor of photovoltaic power generation. Photovoltaic/thermal systems are more effective at concentrating power in areas of high irradiation as compared to traditional PV systems. High irradiation maintains the cell temperature and maximizes electrical-thermal energy. An optimum cooling system is required to remove the extra heat from a PVT system, leading to enhancement of overall performance. In this research, the effect of different high irradiation levels and cooling fluid flow rate are investigated in terms of cell temperature, outlet temperature, electrical-thermal energy and overall performance of PVT system. Finite element based software COMSOL Multiphysics has been used to solve the problem numerically in three-dimensional model. The numerical model has been validated with available experimental and numerical results. It is found that overall efficiency increases with increasing fluid flow rate and with an optimum cooling fluid flow rate of about 180 L/h. Electrical and thermal energy increase from 197 to 983 W and 1165–5387 W respectively, for increasing irradiation from 1000 to 5000 W/m2 with an optimized flow rate of 180 L/h. Electrical, thermal and overall efficiency are found to be about 10.6, 71 and 81.6% respectively, at the highest irradiation level of 5000 W/m2.

Effect of high irradiation on photovoltaic power and energy Wiley, International Journal of Energy Research, 2018 Publication Type: Journal View Summary/Abstract , Publication Link
Solar photovoltaics (PV) is a promising solution to combat against energy crisis and environmental pollution. However, the high manufacturing cost of solar cells along with the huge area required for well-sized PV power plants are the two major issues for the sustainable expansion of this technology. Concentrator technology is one of the solutions of the abovementioned problem. As concentrating the solar radiation over a single cell is now a proven technology, so attempt has been made in this article to extend this concept over PV module. High irradiation intensity from 1000 to 3000 W/m2 has been investigated to measure the power and energy of PV cell. The numerical simulation has been conducted using finite element technique. At 3000 W/m2 irradiation, the electrical power increases by about 190 W compared with 63 W at irradiation level of 1000 W/m2. At the same time, at 3000 W/m2 irradiation, the thermal energy increases by about 996 W compared with 362 W at 1000 W/m2 irradiation. Electrical power and thermal energy are enhanced by about 6.4 and 31.3 W, respectively, for each 100-W/m2 increase of solar radiation. The overall energy is increased by about 179.06% with increasing irradiation level from 1000 to 3000 W/m2. It is concluded that the effect of high solar radiation using concentrator can significantly improve the overall output of the PV module.

Effect of magnetic field on double diffusive natural convection flow in a closed chamber using nanofluid AIP Publishing, AIP Conference Proceedings, 2018 Publication Type: Journal View Summary/Abstract , Publication Link
In the present study, a numerical investigation has been conducted for the effect of magnetic field on double diffusive natural convection flow inside a square enclosure filled with Cu-H2O nanofluid. The governing equations of the present problem have been converted into non-dimensional form using a set of suitable transformation variables and then solved numerically employing Galerkin weighted residual finite element technique. The numerical solution has been carried out for different magnetic field strength, Rayleigh number and volume fraction of nanoparticles with fixed values of controlling parameters. The obtained results are presented in terms of streamlines, isotherms, iso-concentrations and rate of heat transfer. The results indicate that the influence of magnetic field inside the flow region leads to reduce the fluid movement. It is also observed that the heat transfer rate can be enhanced more for the effect of solid concentration of water/Cu nanofluid than water.

Natural convective flow in circular and arc cavities filled with water-Cu nanofluid: A comparative study BanglaJOL, Journal of Naval Architecture and Marine Engineering, 2018 Publication Type: Journal View Summary/Abstract , Publication Link
The fluid flow and heat transfer mechanism on steady state solutions obtained in circular and arc-square enclosures filled with water/Cu nanofluid as well as base fluid has been investigated numerically by Galerkin's weighted residual finite element procedure. The left and right boundaries of the cavities are, respectively, heated and cooled at constant temperatures, while their horizontal walls are adiabatic. Effects of buoyancy force (Rayleigh number) and viscous force (Prandtl number) with a wide range of Ra (103 - 106) and Pr (4.2 - 6.2) on heat transfer phenomenon inside cavities are observed. The fluid flow and temperature gradient are shown by streamlines and isotherms patterns. From the investigation, it is reported that the Rayleigh and Prandtl numbers are playing significant role in heat transfer rate. The variation in heat transfer is calculated in terms of average Nusselt number. Heat transfer rate is found to be higher for water/Cu nanofluid with 2% solid volume fraction than pure water. About 2.7% higher heat transfer rate is obtained for circular cavity than that of arc cavity using water/Cu nanofluid at Ra = 104 and Pr = 5.8.

Mixed convective flow in lid-driven porous cavity: Effect of solid volume fraction Academic Publications, International Journal of Pure and Applied Mathematics, 2018 Publication Type: Journal View Summary/Abstract , Publication Link
The Lid Driven Cavity Flow is most probably one of
the most studied fluid problem in computational fluid dynamics field. Due to the simplicity of the cavity geometry, applying a numerical method on this flow problem in
terms of coding is quite easy and straight forward. Despite
its simple geometry, the driven cavity flow retains a rich
fluid flow physics manifested by multiple counter rotating
recirculating regions on the corners of the cavity depending on the Reynolds number.In this articlemixed convective
heat-mass transfer phenomena is investigated numerically
in a two-sided lid driven square closure. The working fluids are water and water/Cu nanofluid. It is assumed that the
temperature difference driving the mixed convection comes
from the side moving walls, when both horizontal walls
are kept insulated. In order to solve the general coupled
equations, a code based on the Galerkin’s finite element
method is used and it has been validated after comparison
between the present results and those of the literature. To
make clear the effect of using nanofluid on heat and mass
transfers inside the porous enclosure, a wide range of the
nanoparticles solid volume fraction(0% to 3%) is studied.
The phenomenon is analyzed through streamlines, isothermal lines, iso-concentration lines plots, with special attention to the Nusselt number and Sherwood number. It is
found that heat- mass transfer becomes higher by using water/Cu nanofluid than clear water.

Heat-mass transfer of nanofluid in lid-driven enclosure under three convective mode BanglaJOL, GANIT: Journal of Bangladesh Mathematical Society, 2018 Publication Type: Journal View Summary/Abstract , Publication Link
Heat is a form of energy which transfers between bodies which are kept under thermal interactions. When a temperature difference occurs between two bodies or a body with its surroundings, heat transfer occurs. Heat transfer occurs in three modes. Three modes of heat transfer are conduction, convection and radiation. Convection is a very important phenomenon in heat transfer applications and it occurs due to two different gradients, such as, temperature and concentration. This paper reports a numerical study on forced-mixed-natural convections within a lid-driven square enclosure, filled with a mixture of water and 2% concentrated Cu nanoparticles. It is assumed that the temperature difference driving the convection comes from the side moving walls, when both horizontal walls are kept insulated. In order to solve general coupled equations, a code based on the Galerkin's finite element method is used. To make clear the effect of using nanofluid on heat and mass transfers inside the enclosure, a wide range of the Richardson number, taken from 0.1 to 10 is studied. A fair degree of precision can be found between the present and previously published works. The phenomenon is analyzed through streamlines, isotherm and iso-concentration plots, with special attention to the Nusselt number and Sherwood number. The larger heat and mass transfer rates can be achieved with nanofluid than the base fluid for all conditions at Richardson number, Ri = 0.1 to 10. It has been found that the heat and mass transfer rate increase approximately 6% for water with the increase of Ri = 0.1 to 10, whereas these increase about 34% for nanofluid.

Prandtl number effect on nanofluid flow inside a porous cavity THEIIER, Proceedings of The IIER International Conference, 2018 Publication Type: Journal View Summary/Abstract , Publication Link
The problem of lid-driven flows in cavities has been major topic for research studies due to its fundamental nature
and owing to the wide spectrum of engineering applications such as electronic device cooling, crystal growth, highperformance building insulations, multi shield structures used for nuclear reactors, food processing, float glass production,
solar power collectors, furnace, drying technologies, etc. In this article Numerical study of the effect of Prandtl number on
nanofluid flow inside a porous cavity in a two-sided lid driven square closure is studied. The working fluid is Cu/water
nanofluid. By Finite Element Method the governing partial differential equations are solved. The highest Pr causes the
greatest heat and mass transfer. The enhancing performance of heat and mass transfer rate is more effective for the waterCu nanofluid than the base fluid. It is assumed that the temperature difference driving the mixed convection comes from the
side moving walls, when both horizontal walls are kept insulated. In this research, the effect of Prandtl number from 0.71 to
10 on nanofluid flow is investigated. The values of Richardson number, solid volume fraction of water/Cu nanofluid, Darcy
number are kept fixed as 10, 2% and 0.01 respectively. The phenomenon is analysed through streamlines, isothermal lines,
iso-concentration lines plots, with special attention to the Nusselt number and Sherwood number. It is found that heat- mass
transfer becomes higher by using water/Cu nanofluid than clear water.

MHD effect on conjugate heat transfer in a nanofluid filled rectangular enclosure MedCrave, January, 2018 Publication Type: Journal View Summary/Abstract , Publication Link
In the present research a numerical solution has been carried out to investigate the problem
of magnetohydrodynamics (MHD) conjugate natural convection flow in a rectangular
enclosure filled with copper water nanofluid. The relevant governing equations have been
solved numerically by using finite element method of Galerkin weighted residual approach.
The investigation uses a two dimensional rectangular enclosure with heat conducting
vertical wall and uniform heat flux. The effect of Hartmann number on the parameter
Rayleigh number, divider position and solid volume fraction of nano particles on the flow
and temperature fields are examined for the range of Hartmann number (Ha) of 0 to 60.
Parametric studies of the fluid flow and heat transfer performance of the enclosure for the
pertinent parameters have also been performed. The numerical results have been provided
in graphical form of streamlines and isotherms for various dimensionless parameters. It is
found that the heat transfer rate increases with an increase of Rayleigh number and divider
position but it decreases with an increase of the Hartmann number. It is also obtained that
an increase of the solid volume fraction enhances the heat transfer performance. Finally, the
implications of the above parameters have been depicted on the average Nusselt number
of the fluid.

Effect of Conjugate Heat Transfer on Flow of Nanofluid in a Rectangular Enclosure IIETA, June, 2018 Publication Type: Journal View Summary/Abstract , Publication Link
An elaborate numerical study of developing a model regarding conjugate effect of fluid flow and heat transfer in a heat conducting vertical walled cavity filled with copper-water nanofluid has been presented in this paper. This model is mainly adopted for a cooling of electronic device and to control the fluid flow and heat transfer mechanism in an enclosure. The numerical results have been provided in graphical form showing effect of various relevant non-dimensional parameters. The relevant governing equations have been solved by using finite element method of Galerkin weighted residual approach. The analysis uses a two dimensional rectangular enclosure under conjugate convective conductive heat transfer conditions. The enclosure exposed to a constant and uniform heat flux at the left vertical thick wall generating a natural convection flow. The thicknesses of the remaining parts of the walls are assumed to be zero. The right wall is kept at a low constant temperature, while the horizontal walls are assumed to be adiabatic.

Influence of the Periodicity of Sinusoidal Boundary Condition on the Unsteady Mixed Convection within a Square Enclosure Using an Ag–Water Nanofluid MDPI, energies, 2017 Publication Type: Journal View Summary/Abstract , Publication Link
A numerical study of the unsteady mixed convection heat transfer characteristics of an Ag–water nanofluid confined within a square shape lid-driven cavity has been carried out. The Galerkin weighted residual of the finite element method has been employed to investigate the effects of the periodicity of sinusoidal boundary condition for a wide range of Grashof numbers (Gr) (105 to 107) with the parametric variation of sinusoidal even and odd frequency, N, from 1 to 6 at different instants (for τ = 0.1 and 1). It has been observed that both the Grashof number and the sinusoidal even and odd frequency have a significant influence on the streamlines and isotherms inside the cavity. The heat transfer rate enhanced by 90% from the heated surface as the Grashof number (Gr) increased from 105 to 107 at sinusoidal frequency N = 1 and τ = 1.

Unsteady double-diffusive buoyancy-induced flow in a triangular solar collector shape enclosure with corrugated bottom wall: effects of buoyancy ratio Emerald, International Journal of Numerical Methods for Heat & Fluid Flow, 2017 Publication Type: Journal View Summary/Abstract , Publication Link
Purpose
The purpose of this investigation is to determine the nature of the flow field, temperature distribution and heat and mass transfer in a triangular solar collector enclosure with a corrugated bottom wall in the unsteady condition numerically.
Design/methodology/approach
Non-linear governing partial differential equations (i.e. mass, momentum, energy and concentration equations) are transformed into a system of integral equations by applying the Galerkin weighted residual method. The integration involved in each of these terms is performed using Gauss’ quadrature method. The resulting non-linear algebraic equations are modified by the imposition of boundary conditions. Finally, Newton’s method is used to modify non-linear equations into the linear algebraic equations.
Findings
Both the buoyancy ratio and thermal Rayleigh number play an important role in controlling the mode of heat transfer and mass transfer.
Originality/value
Calculations are performed for various thermal Rayleigh numbers, buoyancy ratios and time periods. For each specific condition, streamline contours, isotherm contours and iso-concentration contours are obtained, and the variation in the overall Nusselt and Sherwood numbers is identified for different parameter combinations.

Numerical study on mixed convection heat transfer in a porous L-shaped cavity Science Direct, Engineering Science and Technology, an International Journal, 2017 Publication Type: Journal View Summary/Abstract , Publication Link
A lid-driven L-shaped cavity filled with a porous medium is analyzed. The Galerkin weighted residual method is applied to obtain numerical solutions. The effect of the Reynolds number (Re = 1–100), Grashof number (Gr = 103–105) and Darcy number (Da = 10−5–10−3) on the velocity and temperature fields is examined. For the vertical wall, a higher heat transfer rate is observed when a low Grashof number, higher Darcy number and higher Reynolds number are applied, but the opposite characteristic is found in the horizontal wall. It is evident that heat transfer decreases up to 63% in the horizontal wall when the flow has a high Reynolds number (Re = 100).

Heat transfer detraction for conjugate effect of Joule heating and magnet-hydrodynamics on mixed convection in a lid-driven cavity along with a heated hollow circular plate Scientia Bruneiana , Scientia Bruneiana , 2017 Publication Type: Journal View Summary/Abstract , Publication Link
In this paper, the influence of Joule heating and magneto-hydrodynamics on mixed convection in a lid-driven cavity along with a heated hollow circular plate placed at the centre of the square cavity is investigated. The governing equations which are derived by considering the effects of both Joule heating and magneto-hydrodynamics are solved via the penalty finite-element method with the Galerkin-weighted residual technique. The effects of the Richardson number and Hartmann number arising from the MHD and Joule heating on the flow and heat transfer characteristics have been examined. The results show that the flow behavior, temperature distribution and heat transfer inside the cavity are strongly affected by the presence of the magnetic field. On the other hand, only the temperature distribution and heat transfer inside the cavity are strongly affected by the Joule heating parameter. The results also show that if the Hartmann number is increased from 5 to 100 then the heat transfer detraction is 20%, and if the Joule heating parameter is increased from 1 to 5 then the heat transfer detraction is 58%. In addition, multiple regressions among the various parameters are obtained.

Numerical investigation of pure mixed convection in a ferrofluid-filled lid-driven cavity for different heater configurations Science Direct, Alexandria Engineering Journal, 2016 Publication Type: Journal View Summary/Abstract , Publication Link
Mixed convection has been a center point of attraction to the heat transfer engineers for many years. Here, pure mixed convection analysis in cavity is carried out for two different geometric heater configurations under externally applied magnetic field. Ferrofluid (Fe3O4–water) is considered as working fluid and modeled as single phase fluid. The heaters at the bottom wall are kept at constant high temperature while vertical side walls are adiabatic. The top wall is moving at a constant velocity in both geometric configurations and is kept at constant low temperature. Galerkin weighted residuals method of finite element analysis is implemented to solve the governing equations. The analysis has been carried out for a wide range of Richardson number (Ri = 0.1–10), Reynolds number (Re = 100–500), Hartmann number (Ha = 0–100) and solid volume fraction (φ = 0–0.15) of ferrofluid. The overall heat transfer performance for both the configurations is quantitatively investigated by average Nusselt number at the heated boundary wall. It is observed that higher Ri enhances the heat transfer rate, although higher Ha decreases heat transfer rate. Moreover, at higher Ri and lower Ha, semi-circular notched cavity shows significantly better (more than 30%) heat transfer rate.

Hydromagnetic Double-Diffusive Mixed Convection in Trapezoidal Enclosure Due to Uniform and Nonuniform Heating at the Bottom Side: Effect of Lewis number Science Direct, Alexandria Engineering Journal, 2016 Publication Type: Journal View Summary/Abstract , Publication Link
This paper presents unsteady numerical results of double diffusive mixed convection flow in a trapezoidal enclosure with the uniform magnetic field effect applied in negative horizontal direction. At the bottom wall, the uniform and non-uniform heat and mass are applied while the heat and mass absorbed uniformly at the top wall. Other side walls are impermeable and adiabatic. The top wall moves along x-axis direction with a constant velocity. The transport phenomenon of this problem can be expressed by the coupled governing equation derived from the conservation of mass and momentum along with the energy equation for temperature and concentration. The finite element method (FEM) based on Galerkin weighted residual technique is used to compute the numerical result from these governing equations. The numerical computation is carried out for Lewis number (Le = 0.1–50) and Richardson’s number (Ri = 0.1–100). Computed numerical results of mass, temperature and velocity distribution are expressed graphically as iso-concentration lines, isotherm lines and streamlines respectively. Average Sherwood and Nusselt number values are used to show the mass and heat transfer rate from the heated and concentrated surface of the enclosure. It is found from the analysis that mass transfer strongly depends on Lewis number. Heat and mass transfer for uniformly heated and concentrated bottom wall is larger than the non-uniformly heated and concentrated bottom wall. Finally, a correlation has been done for average Nusselt and Sherwood numbers for both of the cases.

Unsteady Analysis of Natural Convection in a Carbon nanotube-water Filled Cavity with Inclined Heater Taylor & Francis , Numerical Heat Transfer, Part A: Applications, 2016 Publication Type: Journal View Summary/Abstract , Publication Link
A finite element solution has been performed in this work to solve unsteady governing equations of natural convection in a carbon nanotube–water-filled cavity with inclined heater. The temperature of ceiling and left vertical walls is lower than that of the heater while the other walls are adiabatic. The main governing parameters are nanofluid volume fraction and Rayleigh number (Ra). It is found that the heat transfer rate shows different trends based on Rayleigh number and it increases with increase in nanoparticle volume fraction. It has been estimated that average Nusselt number (Nu) is dependent onRa through power regression models with strong positive linear correlation between ln (Nu) and ln (Ra). In particular, for the maximum time, when the solid volume fraction is varied from 0 to 0.1 the dependence between average Nu and linear Ra, on a logarithmic scale, is very high.

Numerical and Statistical Analysis on Unsteady Magnetohydrodynamic Convection in a Semi-circular Enclosure Filled with Ferrofluid Science Direct, International Journal of Heat and Mass Transfer, 2015 Publication Type: Journal View Summary/Abstract , Publication Link
In this paper unsteady magnetohydrodynamic convection has been analyzed using numerical and statistical techniques for a semicircular-shaped enclosure filled with ferrofluid. Cobalt–kerosene ferrofluid is considered for the present investigation. Galerkin weighted residuals method of finite element ananlysis is adopted for the numerical simulation. The effects of Rayleigh number (Ra), solid volume fraction (ϕ) of ferrofluid and Hartmann number (Ha) are considered as pertinent parameters and varied for a wide range of values (Ra = 105–107, ϕ = 0–0.15, Ha = 0–50) to capture the flow and thermal interaction phenomena for unsteady situation. It is observed that higher ferrofluid solid volume fraction escalates the heat transfer rate. Enhancing the intensity of external magnetic field (by increasing Ha) retards the heat transfer rate while increment of Ra exhibits improvement on the heat transfer. It is also found that there exists a strong interacion between ferromagnetic particle (cobalt) and base fluid (kerosene) in the presence of magnetic field which can be utilized properly for desired heat transfer augmentation. If ϕ = 0 (or ϕ = 0.15) and Ra is changed from 105 to 107, the linear dependence of Ψmax on time changes significantly from positive to negative.

In this paper we concentrate to investigate the double diffusive unsteady mixed convection flow in a trapezoidal enclosure in presence of magnetic field. The bottom wall of the enclosure is heated and concentrated uniformly (case-I) and non-uniformly (case-II) while the top wall is cooled and moved uniformly with a constant velocity. Both side walls are adiabatic and impermeable. The coupled governing equations for this phenomenon is solved numerically using weighted residual based Galerkin technique of finite element method (FEM) for Richardson’s number (Ri = 0.1–100) and Buoyancy ratio (Br = −10 to 10) at time τ = 1.0. Reynolds number, Prandtl number and Lewis number are fixed at 100, 0.71 and 10 respectively. Streamlines, isotherm lines and iso-concentration lines are used to show the result graphically for velocity, temperature and mass distribution respectively. Nusselt and Sherwood number values are presented graphically to show the heat and mass transfer rate from the bottom surface of the cavity.

Unsteady natural convection and statistical analysis in a CNT-water filled cavity with non-isothermal heating Science Direct, International Communications in Heat and Mass Transfer , 2015 Publication Type: Journal View Summary/Abstract , Publication Link
A computational study has been done in this work to investigate the effects of CNT–water nanofluids in a cavity with non-isothermal heating for higher Rayleigh numbers. The cavity is heated non-isothermally from the bottom wall, it is cooled from the top and vertical walls are adiabatic. Unsteady governing equations of heat and fluid flow are solved via finite element method for different parameters as Ra and ϕ. A correlation analysis shows that, when controlling for ϕ and τ there was a significant correlation between Ra and Num. When controlling for Ra and ϕ there was a negative significant correlation between τ and Num. It is also found that there is an optimum value for nanofluid volume fraction to control heat transfer, temperature distribution and flow field.

This article focuses on exploring the effect of the magnetic field on double-diffusive mixed convection in a lid-driven trapezoidal enclosure with a uniformly (case I) and nonuniformly (case II) heated and concentrated bottom wall for unsteady flow. Numerical calculation is carried out for different values of Hartmann number (0–50) and Richardson number (0.1–100) at time τ = 1 using the finite-element method (FEM). Temperature, mass, and velocity distribution are expressed graphically as heatlines, masslines, and stream function, respectively. Nusselt and Sherwood numbers are used to demonstrate heat and mass transfer graphically. Better heat and mass transfer were found for case I than case II.

Effect of Sine-squared Thermal Boundary Condition on Augmentation of Heat Transfer in a Triangular Solar Collector Filled with Different Nanofluids Taylor & Francis , Numerical Heat Transfer, Part B: Fundamentals, 2015 Publication Type: Journal View Summary/Abstract , Publication Link
Numerical study of heat transfer phenomena has become a major field of research nowadays. In engineering applications, different boundary conditions arise which have various effects on heat transfer characteristics. For the present work, a triangular-shape cavity has been analyzed for the sine-squared thermal boundary condition which is common in practical cases. The augmentation of heat transfer has been done by introducing a nanofluid inside the cavity. Different solid volume fractions (φ = 0, 0.05, 0.1, 0.2) of water-CuO, water-Al2O3, and water-TiO2 nanofluid have been tested for the cavity with a wide range of Rayleigh number (Ra = 105–108) and for dimensionless time (τ = 0.1 to 1). The Galerkin weighted residual finite-element method has been applied for the numerical solution, and numerical accuracy has been checked by code validation. The heat transfer augmentation for different nanofluids has been done in the light of local (NuL) and overall Nusselt number (Nuav), and the results have been presented with streamline, isotherm, and related contours, in graphs and charts. It has been found that variable boundary condition has significant effect on flow and thermal fields and increase of solid volume fraction enhances the heat transfer.

Simulation of unsteady heat and mass transport with heatline and massline in a partially heated open cavity Science Direct, Applied Mathematical Modelling, 2015 Publication Type: Journal View Summary/Abstract , Publication Link
A computational work is performed to investigate the transient heat and mass transfer inside a ventilated enclosure. The enclosure has two ventilation ports as inlet and outlet. Three different configurations are tested according to location of outlet ports while location of inlet port is fixed. In case 1, the outlet port is located on the top of the left vertical wall, in case 2 at the right and case 3 at the middle of the ceiling. Finite element method is employed to solve the governing equations of flow, heat and mass transfer. Also, the heatline and massline techniques are used to visualize the heat and mass transfer patterns. Obtained results show the evolution of various contours of stream function, isotherms and iso-concentrations as well as various parameters such as Nu and Sc numbers. It is found in particular that in order to reach highest heat and mass transfer rates for Gr = 107, the outlet port should be located near the top of the left vertical wall. On the other hand, the effect of outlet location is insignificant for the lower values of Gr.

Unsteady Mixed Convection in a Porous Media Filled Lid-Driven Cavity Heated by a Semi-Circular Heaters semanticscholar, THERMAL SCIENCE, 2015 Publication Type: Journal View Summary/Abstract , Publication Link
A computational study has been performed on natural convection heat transfer and fluid flow in a porous media filled enclosure with semi-circular heaters by using finite element method. The ceiling of the cavity moves with a constant velocity and it is insulated. Vertical walls temperature is lower than that of heaters. Results are presented via streamlines, isotherms, average Nusselt numbers, and cross-sectional velocity for different governing parameters such as Richardson and Darcy numbers, and dimensionless time. It is observed that both circulation of the flow and heat transfer is strongly affected with time increment and Darcy number inside the cavity.

ON PRIME AND SEMIPRIME GOLDIE MODULES World Scientific, June, 2011 Publication Type: Journal View Summary/Abstract , Publication Link
A right R-module M is called a Goldie module if it has finite Goldie dimension and satisfies the ACC for M-annihilator submodules of M. In this paper, we study the class of prime Goldie modules and the class of semiprime Goldie modules as generalizations of prime right Goldie rings and semiprime right Goldie rings.
