Heat source and radiation absorption on unsteady MHD fluid flow over an infinite vertical plate embedded in a porous medium in presence of Soret effect

Abstract

In this paper, an investigation on the heat source and radiation absorption on MHD fluid flow past an accelerated vertical plate embedded in a porous medium with variable thermal diffusion are carried out. The dimensionless governing equations are solved using closed form of Laplace transformation technique. The velocity, temperature, concentration profiles, Nusselt number and Sherwood number are graphically interpreted to various physical parameters like thermal Grashof number, time, Accelerating parameter, Prandtl number and Permeability parameter, Magnetic parameter, Schmidt number, Mass Grashof number and Soret number etc. It has been found that velocity, concentration and Nusselt number rise with the increasing Prandtl number. Further, temperature and Sherwood number decreases with increment in Prandtl number.
