• THERMAL RADIATION AND ROTATION EFFECT ON AN UNSTEADY MHD MIXED CONVECTION FLOW THROUGH A POROUS MEDIUM WITH HALL CURRENT

Abstract

The effect of thermal radiation and rotation on an unsteady magnetohydrodynamic mixed convection flow through a porous medium with hall current has been studied. The similarity solutions were obtained using suitable transformations and the resulting similarity partial differential equations were solved by using Galerkin finite element method.. A uniform magnetic field is applied in the direction normal to the planes of the plates. The entire system rotates about an axis normal to the planes of the plates with uniform angular velocity . The temperature of one of the plates varies periodically and the temperature difference of the plates is high enough to induce radiative heat transfer. The effects of various parameters on the velocity profiles, the skin friction, temperature field, rate of heat transfer in terms of their amplitude and phase angles are shown graphically.
