摘要

The present study is conducted to investigate the local heat/mass transfer charac- teristics and local film cooling effectiveness around a conical-shaped film cooling hole with compound angle orientations. The cylindrical hole and two types of shaped hole with conically-enlarged hole exits are used to investigate the effect of film cooling hole geometry. One shaped hole (shaped hole # 1) expands 4°in all directions from the middle of hole to the exit.
