Note (General): Experiments were made on film cooling with injection through holes located near the leading edge of a model in a low-speed, room-temperature wind tunnel. The model, which simulates the leading edge portion of an air-cooled turbine blade section, consists of a semicircular cylinder with four rows of blowing holes and two flat plates forming the upper and lower surfaces of its body. The change of flow coefficient of the blowing holes, the pressure distributions and the temperature distributions(film cooling effectivenesses) along the surface of several models were measured. It is proved that the inclination of the blowing holes in the spanwise direction shows very high effectiveness, but that excessive injection sometimes lowers the effectiveness. The film cooling effectiveness of the experimental model and of an air-cooled turbine nozzle are calculated by means of an approximate method.
