• RADIATIVE AND FREE CONVECTIVE EFFECTS ON MHD FLOW THROUGH A POROUS MEDIUM WITH PERODIC WALL TEMPERATURE AND HEAT GENERATION OR ABSORPTION

Abstract

Aim of the paper is to investigate magnetohydrodynamic free convection and oscillatory flow through a vertical channel filled with porous medium and non-uniform wall temperatures. Also the effect of radiation and heat generation or absorption on an electrically conducting optically thin fluid is demonstrated analytically and quantitatively. For an oscillatory time-dependent coupled non-linear equations are solved for the fluid velocity and temperature by asymptotic approximation. Numerical results for the velocity and temperature profiles for various parameters such as Grashof number, radiation parameter, porosity parameter, Prandtl number and heat generation/absorption parameter as well as local skin friction coefficient and local Nusselt number are discussed numerically and presented through graphically.
