Three - Dimensional MHD Flow and Heat Transfer Through a Porous Medium with Periodic Permeability


Dr.G. Venkat Reddy, Dr.R. RaghavendraRao
Abstract

A three - dimensional MHD flow and heat transfer of a viscous, incompressible, conducting fluid, through a semi infinite porous medium, in the presence of viscous dissipative heat, is considered. The porous medium is bounded by an infinite porous flat surface, kept at a uniform temperature. The cross flow (suction) velocity at the surface is assumed to be constant. A uniform magnetic field of strength (H0) is applied normal to the bounding surface. The expressions for the velocity, temperature profiles are obtained using the perturbation method. The expressions for shear stress and Nusselt number are derived from the velocity and temperature expressions. The numerical results are shown graphically for various parameters such as the velocity ratio parameter , Reynolds number (R), Prandtl number (P), Eckert number (E), the permeability parameter (K) and the Hartmann number (M). The skin friction factor F1 and the rate of heat transfer factor F2 are also obtained and numerical results are shown in graphs.
