EXACT SOLUTION OF MAGNETOHYDRODYNAMIC SLIP FLOW AND HEAT TRANSFER OVER AN OSCILLATING AND TRANSLATING POROUS PLATE

Objective of this paper is to study natural convection MHD flow past over a moving porous plate with heat source in the porous medium. The motion of the plate is translating as well as oscillating and embedded in the porous medium. The exact solution of the governing equations, of the flow and heat transfer for this model is obtained. To study heat flux for our model we use Nusselt number. Comparisons of effects of magnetic parameter M, translation a and heat source parameter S on velocity and temperature profile is given. The effects of some other physical parameters like Prandtl number P-r, Grash of number for heat transfer G(r), Permeability parameter Kp, is presented graphically on the distributions of velocity and temperature. It is concluded that the fluid motion in the boundary layer increases with increase of a, S, G(r) and Kp. Whereas opposite behavior is observed for M and P-r. The heat source parameter increases the temperature of fluid and on the other hand cooling effects occur due to P-r and v0.
