A numerical procedure previously developed to simulate heat transfer with full-coverage film cooling has been successfully applied to film cooling geometries that incorporate single, double, and multiple rows of cooling holes. The procedure is based on the STAN5 boundary layer program with models added to simulate film coolant injection and turbulence augmentation. Experimental data for comparison have been extracted mostly from the open literature, and the data represent a wide variety of film cooling geometries. Both spanwise-averaged film cooling effectiveness and heat transfer data are considered. Linear superposition theory for film cooling is tested by comparing superposition predicted effectiveness with the experimental values.
