Abstract

The transient heat transfer near a two dimensional stagnation-point in a steady flow of a viscous and incompressible fluid is considered. The temperature of the fluid is assumed to change abruptly from a constant to another constant. Two cases are investigated by means of Liepmann's approximate method. In the first case the temperature of the wall is assumed to be a constant and in the second case the rear surface or the thin wall to be adiabatic. The time histories of the heat transfer coefficient for both case and of the temperature of the wall for the second case are obtained. Discussions on the validity of the latter are given.
