Soret Effect on an MHD Free Convective Mass Transfer Flow Past an Accelerated Vertical Plate with Chemical Reaction

摘要

An exact solution to the problem of an MHD heat and mass transfer flow with Soret effect past an accelerated infinite vertical plate embedded in a porous medium in presence of chemical reaction is presented. A magnetic field of uniform strength is applied normal to the plate directed into the fluid region. The governing equations are solved by Laplace-Transform technique in closed form. The expressions for the velocity field, the temperature field, the concentration field, the coefficient of skin friction at theplate in the direction of flow and the coefficient of heat and mass transfer in terms of Nusselt number and Sherwood number at the plate are obtained and their nature are demonstrated graphically for different values of the parameters involved in the problem. It is found that the Soret effect or thermal diffusion effect has a significant role in controlling the flow and heat and mass transfer characteristics.
