Abstract

The main objective of this paper is the unsteady MHD free convection heat and mass transfer for a heat generation/absorption with radiation absorption in the presence of a reacting species over an isothermal vertical plate has received little attention. Hence the main objective of this paper is to investigate the effects of thermal radiation, chemical reaction, heat source of an electrically conducting fluid past an isothermal vertical porous plate subjected to variable suction. The mathematical model, derived from the Navier-Strokes equation was reduced to a system of coupled partial differential equation for velocity, temperature and concentration using Boussinesq‘s approximation. The dimensionless governing equations are tackled using the usual perturbation technique. Also, the effects of velocity, temperature and concentration fields were intercepted for various physical parameters with the help of graphs.
