Effects of Chemical Reaction and Thermal Diffusion on Mixed Convective Mass Transfer Flow in Permeable Media with Heat Generation/Absorption

The present paper analytically deals with two dimensional steady incompressible viscous flow of Newtonian fluid past a permeable plate immersed in Darcian porous media in presence of first-order chemical reaction, thermal diffusion (Soret) and heat generation/absorption effects. The primary velocity is found to increase due to increase in parametric values of thermal diffusion, permeability parameter, while the increase in Schmidt number and chemical reaction parameter decrease the flow rate. It is also seen that the mass transfer rate accelerates under the influence of Schmidt number and chemical reaction parameter, whereas the skin-friction increases as thermal diffusion parameter increase and decreases due to increase in chemical reaction parameter.
