Abstract

The objectives of the present study are to investigate the effect of flow parameters on free convection and mass transfer unsteady magnetohydrodynamic flow of an electrically conducting,viscous,in compressible fluid pastan infinite vertical porous plate under oscillatory suction velocity and thermal radiation by taking into account the Dufour (diffusion thermo) and Soret (thermal diffusion) effects.The problem is solved numerically by using finite element method for velocity,temperature and concentration field and also the expression for skin friction,rate of heat and mass transfer have been obtained.The results obtained have been presented numerically through graphs and tables for externally cooled plate (Gr>0) and externally heated plate (Gr<0) to observe the effects of various param eters encountered in the equations.
