Summary: This paper investigates the effects of velocity, temperature, and solutal slip on the mass and heat transfer characteristics of MHD mixed convection Casson fluid flow along an exponential permeable stretching surface. The governing equations, representing momentum, energy, and species concentration, are converted into ordinary differential equations using the similarity transformation. The ODEs are then numerically solved using the Keller-box method. The impacts of altered physical characteristics on flow quantities are explored through graphs and tables.

Summary: This article explores the series solution of magnetohydrodynamics by using the homotopy analysis method, focusing on the flow of a first-order chemically reacting Maxwell fluid past a stretching sheet in a porous medium. The impact of various physical factors on the flow model is vividly presented, and the error graphs show that the residual profiles decrease more sharply as the number of iterations increases.

Summary: This study explores the effects of thermal diffusion, diffusion-thermal energy, Brownian motion, thermophoresis, Prandtl number, magnetohydrodynamics, and radiation on a Maxwell fluid near a stretching cylinder. The study aims to investigate the impact of these factors on the behavior of critical parameters and utilizes MATLAB software for visualization. Both flat plate and cylinder geometries are considered, and the study concludes that concentration profiles show opposite behaviors to thermophoresis, Brownian motion, and the Dufour effect, while temperature profiles increase for these parameters and concentration increases with the Soret number.

Summary: This study proposes a unique model to investigate the unsteady stagnation point flow in a hybrid nanofluid induced by an exponentially permeable stretching/shrinking sheet with a magnetic field. The results show that the skin friction coefficient and local Nusselt number increase by enhancing the suction/injection parameter and nanoparticles volume fraction.

Summary: The Dufour and Soret effects on the flow of a Casson fluid about an unsteady radially stretched sheet are analyzed. The solution to the nonlinear ordinary differential equations is calculated using artificial neural networks. The results suggest that the artificial neural network-based method gives significant accuracy and that the solution's efficacy increases as the number of neurons in the neural network increases.

Summary: The study investigated the effect of a non-uniform heat source/sink on the unsteady stagnation point flow of Carreau fluid past a permeable stretching/shrinking sheet, incorporating additional effects of magnetohydrodynamics, joule heating, and viscous dissipation. The nonlinear partial differential equations were transformed into ordinary differential equations and solved using the Runge-Kutta-Fehlberg technique. The results showed how the fluid flow velocity and temperature of Carreau fluid varied with different parameters, and how the local Nusselt number changed with the Eckert number for both upper and lower branches.

Summary: A numerical investigation of unsteady boundary layer flow with heat and mass transfer of non-Newtonian fluid model is carried out in this study, considering the significance of Soret and Dufour effects. The results show excellent agreement between the numerical results obtained by the local nonsimilarity method and homotopy analysis method. A new mathematical approach to obtain the solutions of unsteady-state flow with heat and mass transfer phenomenons is established. The study also discusses the effects of different emerging parameters and presents the variations of dimensionless quantities such as skin friction coefficient, Sherwood number, and Nusselt number.

Summary: This study investigates the heat transfer characteristics of MHD hybrid nanofluid over a linear stretching and shrinking surface with suction and thermal radiation effects. The study finds that the heat transfer efficiency of the hybrid nanofluid is greater than the nanofluid, and dual solutions exist for a specific range of the stretching/shrinking parameter. Additionally, the skin friction coefficient and local Nusselt number increase with suction effect, and suction and thermal radiation widen the range of the stretching/shrinking parameter for which solutions exist.

Summary: This paper numerically investigates the effects of Dufour and thermal diffusion on unsteady MHD free convection and mass transfer flow through an infinite vertical permeable sheet. The study shows that increases in the suction parameter decrease the velocity field, while the thermal boundary layer thickness decreases with rising values of the Dufour and Soret numbers. The skin friction increases with higher Soret and Dufour numbers but decreases with suction parameter, Magnetic force number, Prandtl number, and Schmidt number.

Summary: This study investigates the MHD convective Walters-B memory liquid flow past a permeable accelerating surface with the mechanism of Soret-Dufour. By simplifying the flow equation to total differential equations and using the spectral homotopy analysis method, the outcomes of the model are obtained. The results show that the imposed magnetism decreases the velocity distribution, while the thermal radiation term increases the temperature distribution.

Summary: In this study, the steady and incompressible MHD movement of a viscous nanofluid past a non-linear stretching plate, considering heat generation and the presence of a permeable medium, was mathematically investigated. The impacts of porosity and heat generation were explored, and numerical solutions were obtained using MATLAB software. The results showed that porous media parameter affected the velocity profile, while the temperature and mass distribution exhibited contrasting responses. The findings of this study can be applied to the design of high-temperature processing operations.
