Abstract
In this study, we investigate the heat and mass transfer characteristics of an unsteady mixed convection magnetohydrodynamic (MHD) flow of Casson fluid through a porous medium in the presence of thermal diffusion and heat source effects.The flow is considered between isothermal inclined plates, incorporating the influences of Joule heating and viscous dissipation.Using dimensionless variables, the governing partial differential equations are transformed into their dimensionless form.The resulting dimensionless equations are solved empirically through the perturbation methodology.The effects of various critical parameters on the velocity, temperature, and concentration distributions within the boundary layer are analyzed with the aid of graphical representations.Additionally, numerical values of skin friction, Nusselt number, and Sherwood number near the plate are examined for different parameter values and presented in tabular form.The findings provide a deeper understanding of heat and mass transfer mechanisms in MHD flows through porous media, which are relevant to various industrial and engineering applications.
