Abstract
This paper deals with a numerical investigation of the film cooling effectiveness on five different curved surfaces and a flat surface. The models consist of 11 rectangular cross-sectioned injection holes aligned in a single row. The blowing ratios are from 0.5 to 2.0, and the injection angle with respect to the horizontal plane is 30°. The hole geometry, the slope of the curved surface and the blowing ratio have important effects on the film cooling effectiveness. The results show that the film cooling effectiveness of a given curved surface, both along the mainstream and the spanwise direction, depends on the optimum selection of the parameters mentioned above.
