Abstract: 

An attempt has been made to investigate the Soret effects in a MHD free Convective Flow through a porous medium bounded by an infinite vertical porous plate with constant heat flux and a magnetic field of uniform strength is applied perpendicular to the plate. The governing equations are solved by regular perturbation technique. The expressions for the velocity distribution, temperature field, skin friction, and species concentration are obtained and the effects of the different parameters namely Soret number Sr. Hartmann number M, Grashof number for heat transfer Gr, Grashof number for mass transfer Gm, Prandtl number Pr on these fields are demonstrated graphically and the results are discussed. Increasing the Soret number Sr increases the velocity profile, temperature and concentration.
