摘要：

This study attempts to explore a qualitative analysis of the effects of Soret on an unsteady magnetohydrodynamics free convection flow of a chemically reacting incompressible fluid past an infinite vertical plate embedded in a porous medium taking the source of heat and thermal radiation into account as well as viscous dissipation. The central equations are scrupulously converted into sets of coupled nonlinear partial differential equations for providing logical solutions. The method of Galerkin finite element is used considering appropriate boundary conditions for diverse physical metrics and then numerically analyzed employing MATLAB. A significant change in velocity, temperature, concentration profiles is observed for various values of Prandtl number, Grashof number, Eckert number, Soret number. It is noticed that the velocity profile enhances by enhancing the values of porous medium as well as it decreases when ‘M’ and Prandtl number increases. The temperature profile decreases as for the increasing vales of heat source parameter and also the concentration profile increases as Soret number increases. © 2021, Global Digital Central.
