MHD Mixed Convection Flow Past a Vertical Porous Plate in a Porous Medium with Heat Source/Sink and Soret Effects

Abstract

The present analysis is to study the boundary layer flow of an incompressible, steady combined free-forced convection and mass transfer flow over a vertical porous plate embedded in a porous medium with the effects of heat source/sink, suction/injection and thermal diffusion under the influence of magnetohydrodynamics. The uniform magnetic field is applied along the plate. With the help of similarity transformations the partial differential equations are transformed into a coupled non-linear ordinary differential equations, which are solved numerically by applying the implicit finite difference scheme known as Keller Box method. The effects of physical parameters on velocity, temperature and concentration profiles are illustrated graphically showing the effects of the different parameter values of the magnetic field, suction, local heat source/sink, permeability parameters, Soret number and Schmidt number. Finally, the numerical data for the local skin friction    coefficient, the coefficient of local Nusselt number and coefficient of local Sherwood numbers also have been tabulated.
