MHD Free Convective Boundary Layer Flow through Porous medium Past a Moving Vertical Platewith Heat Source and Chemical Reaction

Abstract

In this paper, we have considered the unsteady magnetohydrodynamic (MHD) free convection in a boundary layer flow of an electrically conducting fluid through porous medium subject to uniform transverse magnetic field over a moving infinite vertical plate in the presence of heat source and chemical reaction. The equations for governing flow through porous medium based on Brinkman’s model. The non-linear partial differential equations have been transformed into a two point boundary value problem using similarity variables and then solved numerically by Runge-Kutta fourth order method with the help of shooting technique. Computational results are discussed for velocity, temperature and concentration profiles while numerical values of the skin friction, Nusselt number and Sherwood number are tabulated for different values of governing parameters controlling the flow system.
