Effects of chemical reaction and heat absorption on hydromagnetic flow past a moving plate through porous medium with ramped wall temperature in the presence of Hall current and thermal radiation

Abstract

This paper deals with the study of effects of chemical reaction and heat absorption on an unsteady free convective flow of a viscous, incompressible, electrically conducting and optically thin fluid past an infinite vertical moving plate through porous medium with ramped wall temperature in the presence of Hall current and thermal radiation. The governing equations are converted into non-dimensional form and then solved by using the Laplace transform technique. The expressions are obtained for fluid velocity, fluid temperature, species concentration, skin friction, Nusselt number and Sherwood numbers. Effects of pertinent flow parameters are presented graphically and discussed quantitatively. It is found that the increase in chemical reaction and heat absorption parameters contribute in thinning the momentum and thermal boundary layers.
