MHD unsteady free convection boundary layer flow with dissipation and chemical reaction through a porous medium under slip boundary conditions

Abstract

In the present paper chemical reaction effects as well as viscous heat dissipation on the transient free convection and mass transfer flow of an electrically conducting, viscous, incompressible fluid, past an infinite vertical porous plate, in presence of uniform externally applied transverse magnetic field. Moreover, at the plate there is slip for velocity field and jump in temperature field. The concentration is assumed to be oscillating with time. Adopting a perturb bative series expansion about a small parameter, I, expression are obtained and are shown graphically describing the velocity, temperature, skin-friction coefficient and the rate of heat transfer. It is being observed that Nusselt number increase with increase in chemical reaction parameter.
