COMPARISON OF COOLING EFFECTIVENESS OF TURBINE VANES WITH AND WITHOUT FILM COOLING

摘要

The cooling effectiveness of three film-cooled vanes were compared to the cooling effectiveness of two non-film-cooled vanes. The comparison indicated that, for the vane configurations and test conditions examined, film cooling had an adverse effect near the suction surf ace trailing edge of the vanes. Film cooling was found to be beneficial on the pressure surface of the vanes.
