Soret Effect on Mhd Natural Convection Flow With Radiative Heat Transfer Past An Impulsively Moving Plate With Ramped Wall Temperature Through Porous Medium

The effect of thermo-diffusion (Soret effect) on unsteady hydromagnetic free convective flow of a viscous, incompressible, electrically conducting and optically thick radiating fluid past an infinite vertical plate in a porous medium is analyzed in the present study. An impulsively moving infinitely long vertical plate with ramped temperature distribution on its surface is taken. The exact solutions of governing dimensionless partial differential equations are obtained by using Laplace transform technique. The effects of pertinent flow parameters on velocity, temperature and concentration profile are numerically evaluated, graphically depicted and discussed. In case of skin friction, Nusselt number and Sherwood number, numerical values are presented in tabular form. Results disclosed that fluid velocity and species concentration in the boundary layer region enhanced with Soret effect.
