Abstract

In this paper the effect of free convection on the heat transfer and the flow through a highly porous medium bounded by two vertical parallel porous plates in presence of transverse magnetic field is studied. It is assumed that free stream velocity oscillates in times about a constant mean. Assuming periodic temperature at the moving plate, the approximate solutions for velocity and temperature are obtained and the effect of various physical quantities are studied through graphs. The expressions for skin friction and the rate of heat transfer are also obtained and discussed through tables.
