Abstract

Abstract

The local and the overall convective heat transfers inside the small holes have been investigated experimentally for the inclined multihole wall film cooling,according to the similarity theory.The results demonstrate that the convective heat transfer intensifies very greatly in the region inside the hole entrance.The results also reveal that the Renolds number of the hole has strong influence on the convective heat transfer.The higher the Renolds number,the more intensive the convective heat transfer inside the hole.
