Heat transfer over an unsteady stretching permeable surface with prescribed wall temperature. (English) Zbl 1162.76017

Summary: We investigate the unsteady laminar boundary layer flow over a continuously stretching permeable surface. The unsteadiness in the flow and in the temperature field is caused by the time-dependence of the stretching velocity and of the surface temperature. We examine the effects of unsteadiness parameter, suction/injection parameter and Prandtl number on heat transfer characteristics.
