Abstract

In this work, we have undertaken to study heat and mass transfer in MHD convective flow past an infinite plate with porous media in existence of radiation, thermal diffusion effect and heat sink. A uniform strength of magnetic field was used transversely in the fluid region. The originality of this work is to examine the thermal diffusion effect on the flow incidents in case of heat sink or thermal radiation. The principal equations are solved by perturbation technique to get statements for velocity, temperature, and concentration fields. In this paper we also consider several physical quantities on the flow domain graphically as well as tabularly which have been studied previously by other researchers except few new cases like light velocity and temperature relationship from different sources such as density gradient effect which are being discussed herein for first time.
