Abstract: This paper seeks to explore the effect of chemical reaction and thermal radiation on steady MHD mixed convective flow of a viscous, incompressible, electrically conducting fluid which passes through an infinite vertical porous plate. A uniform magnetic field is applied in transversely to the direction of the flow in presence of a heat source. The perturbation technique is used to solve the non-dimensional governing equations. The effects of thermal radiation, thermal-diffusion; heat source and chemical reaction on the characteristics of the flow are studied graphically. It is seen that the effects of thermal-radiation and chemical reaction have a significant role in controlling the flow pattern, the heat and mass transfer characteristics of the flow.
