Abstract

Results of experimental study of the effect of external turbulence (7 %) on the film cooling efficiency over the flat plate with coolant supply into shallow indentations of different shape namely – craters, trench, semispherical segments, were presented. It is shown that the effect of external turbulence for the investigated schemes is relatively low in comparison with holes without indentations.
