Abstract
The present paper deals with the theoretical study of thermal radiation and chemical reaction on free convective heat and mass transfer flow of a Newtonian viscous incompressible fluid past a suddenly accelerated semi–infinite vertical permeable plate immersed in Darcian absorption media. The fluid media is considered as optically thick and the Rosselend radiative heat flux model is incorporated in the energy equation. The governing equation of motions are first non-dimensionalised and then transformed into a set of ordinary differential equations by employing a suitable periodic transformation. The closed form of the expression for velocity, temperature and concentration fields as well as skin- friction, Nusselt and Sherwood numbers are obtained in terms of various physical parameters present. The effect of parameters like thermal radiation, first order chemical reaction, radiation absorption co-efficient and permeability parameter on the flow variables are obtained numerically and illustrated through graphs and tables. It is observed that, the absorption parameter and radiation parameter increase the temperature as well as the fluid velocity, while the skin–friction is found to be decreasing due to an increase in thermal radiation parameter. It is also observed that, some of the transportation phenomena accelerate due to the presence of chemical reaction parameter.
