UNSTEADY MAGNETOHYDRODYNAMIC OSCILLATORY FLOW AND HEAT TRANSFER ANALYSIS OF A VISCOUS FLUID IN A POROUS CHANNEL FILLED WITH A SATURATED POROUS MEDIUM

摘要

In this article, unsteady oscillatory flow of a magnetohydrodynamic fluid and heat transfer analysis with nonuniform wall temperature through a planar channel filled with a saturated porous medium are studied. It is assumed that the walls of the channel are porous so that suction/injection may take place. The exact analytic closed-form solution is obtained for velocity and temperature fields. The mathematical results are then plotted to see the effect of different parameters on the flow phenomenon.
