Film cooling is a major cooling technique for turbine cooling. Flow field of film cooling is very complex and results calculated by RANS don't match experimental results. This paper describes calculating this flow by two turbulent model (Spallart-Allmarous(SA) and shear-stress transport(sst) model) and clearing how RANS results don't match experimantal results and difference betwwen SA and sst results. Calculated configuration is a film cooling of a flat plate in which coolant air is injected from a plenum through one row of inclined circular holes. This paper's CFD results don't match experimantal results at centerline film efficiency but averaged film efficiency. Different turbulent model(SA and sst) results match almost each other.
