    Abstract

  • A low-cost, high-precision experimental verification platform of film cooling effect was designed. The high-speed and high-temperature flame impact experiment was carried out for the film holes with different structures of plate samples. The infrared temperature measurement technology was used to collect and analyze the temperature field of the plate. The results showed that the temperature gradient in x direction of the two hole shapes was smaller than that in y direction, but the cat-ear hole had better cooling effect in y direction; The x-direction comprehensive cooling efficiency of cat-ear hole was also better than that of cylindrical hole, and the cooling air flow was inclined to form a stable film cover; In addition, the overall cooling effect of cat-ear hole in unit area was better than that of cylindrical hole, but greater thermal stress may occur near the outlet of cold air. The cooling area of cat-ear hole film cooling was also larger than that of cylindrical hole.
