Abstract

Abstract

The film-cooling uniformity of discrete holes in the direction normal to main stream is investigated by means of heat and mass analogy. At different blowing ratios, the features of the film-cooling uniformity for one row and two rows of discrete holes are compared. It is found that the film-cooling uniformity on the concave surface is better than that on the convex one.
