| Abstract: | Unsteady hydromagnetic thermal boundary layer flow past a non-conducting infinite porous wall in presence of a transverse magnetic field is considered. The magnetic Reynolds number of the flow is taken to be small enough so that the induced magnetic field is negligible. It is assumed that the normal velocity of suction/injection at the wall varies att ?/12. Solution of the problem, in the form of power series, is obtained for two cases: - When the wall temperature is the same as that of the free-stream, and
- When the difference in the temperatures of the wall and that of the free-stream varies as some power of time. The variations of the skin-friction, the temperature and the rate of heat transfer are shown graphically followed by a quantitative discussion.
