In this paper, we investigated the combined radiation and Ohmic heating effects on MHD free convective Visco-elastic fluid flow past a porous plate with viscous dissipation. The governing equations are solved for the velocity profile, temperature and concentration by using double perturbation technique. The effects of magnetic parameter M, Grashof number Gr, modified Grashof number Gm on velocity u are shown in the graphs while the effects of these parameters on skin friction are numerically discussed through tables.

Keywords: Grashof number; modified Grashof number; MHD; Ohmic heating; Visco-elastic fluid; viscous dissipation.
