Experimental studies on the film cooling effectiveness of turbulent flow over an adiabatic flat plate have been carried out. Schiieren photographs for different flow rates are given. Experimental studies of the heat transfer coefficient of an electrically heated flat plate are compared with theoretical results. The fluctuating velocity and turbulence intensity distributions at different sections of the nonisothermal film cooling flowfield were measured by a hot film anemometer. The film cooling effectiveness equations can be modified by the turbulence mixing coefficient.
