Experimental investigations were conducted in order to clarify some of the problems of film cooling of an adiabatic flat plate in zero pressure gradient downstream of a tangential injection slot. The experimental conditions were a hot mainstream and cold secondary injection. Results are presented for wall temperature distributions at varying injected-to-mainstream mass flow ratios. Results are also presented of boundary layer temperature and velocity profiles in film cooling, for an injected-to-mainstream mass flow ratio of 0.88. The existing literature available in film cooling is reviewed.
