In the present paper, the problem of a steady two dimensional hydromagnetic convective flow of a viscous, incompressible electrically conducting fluid past an inclined plate in porous medium has been studied. The convective flow starts under the simultaneous action of the buoyancy forces caused by the variations in density due to temperature and species con-centration differences. The effects of viscous dissipation have been taken into account and the partial differential equations governing the boundary layer flow are converted into a system of ordinary differential equations by using suitable similarity transformations. These equations are solved numerically and effects of various parameters on the flow fields are investigated and presented graphically.
