• RADIATION EFFECTS ON STEADY HYDROMAGNETIC FLOW OF A VISCOUS FLUID THROUGH A VERTICAL CHANNEL IN A POROUS MEDIUM WITH HEAT GENERATION OR ABSORPTION

Abstract

This paper investigates the combined effects of radiation and heat generation or absorption on steady hydromagnetic flow of an electrically conducting optically thin fluid through a vertical channel filled with porous medium and non-uniform wall temperatures. Analytical solutions are obtained for the governing coupled dimensionless partial differential equations of velocity and temperature. Numerical results for velocity and temperature are presented graphically and the numerical values of skin-friction and Nusselt number have been tabulated. The effect of different parameters like thermal Grashof number, radiation parameter, porosity parameter and heat generation/absorption parameter on velocity, temperature, skin-friction and Nusselt number are discussed.
