Thermal diffusion and chemical reaction effects on unsteady flow past a vertical porous plate with heat source dependent in slip flow regime

The present study investigates an analytical solution of free convective unsteady fluid flow in the presence of thermal diffusion and chemical reaction past a vertical porous plate with heat source dependent in slip flow regime. the plate is assumed to move with a constant velocity in the direction of fluid flow while free stream velocity is assumed to follow exponentially increasing small perturbation law. the velocity,temperature,and concentration profiles are presented graphically for different values of the parameters entering into the problem. finally,the effects of pertinent parameters on the skin friction coefficient,nusselt number,and sherwood numbers are studied and are shown through graphs and tables by using perturbation technique. it is observed in the case of air that the temperature decreases very rapidly whereas,in the case of liquid,the temperature decreases steadily. © 2016 aname publication. all rights reserved.
