Keywords:
film cooling, hemispherical dimples, trench, blowing ratio, film cooling effectiveness, numerical simulation.
Abstract
The results are given towards the theoretical investigation of the film cooling efficiency of single-row hole systems with the supply of a coolant through holes arranged in the trench, hemispherical dimples, as well as through traditional cylindrical inclined holes.
