Khalatov, I. Borisov, Yu. Dashevskiy, A. Kovalenko, S. Shevtsov] Results of an experimental study of a flat plate film cooling efficiency from a single row of inclined holes embedded in a "shallow” trench are presented. It is shown the cooling efficiency of such a configuration is much greater than that of the traditional configuration of inclined round holes. This provides more uniform surface coverage by the coolant film. The flow external turbulence increases the film cooling efficiency by 5-8%, while the freestream flow acceleration reduces it by 10-15%.
