Abstract

Results of the flow acceleration influence on the film cooling are given for a few variants of coolant supply through a slot, cylindrical or shaped holes, and holes in shallow indentations of different shape - craters, trench, semispherical segments. The correlations for film cooling efficiency prediction are presented.
