Abstract

Abstract

The experimental results and numerical computation of film cooling effectiveness downstream of injection from two staggered rows of holes are presented in this paper.On the basis of measured effectiveness in both streamwise and spanwise directions,especially in the region close to injection holes,the different heat transfer behaviors of the jets from upstream and downstream rows are analyzed.In the computation,a three dimensional calculation procedure is used to solve the related elliptic equations and the results agree well with present measurements far downstream.The discrepancies are increased in the near injection region.
