Abstract

An unsteady MHD free convective fluid flow of a viscous incompressible and electrically conducting fluid past a vertical porous plate in the presence of suction or injection is considered. The non–linear partial differential equations governing the flow have been solved numerically using finite difference method. The effect of Ohmic heating, on the velocity and temperature distributions and also on the mass transfer is comprehensively discussed in this paper. The effects of the various parameters on the velocity, temperature and concentration profiles are presented graphically and values of skin– friction coefficient, Nusselt number and Sherwood number for various values of physical parameters are also analyzed through tables.
