Introduction to film cooling; three dimensional film cooling; curvature effects and film cooling
Abstract
Graphs and tables show the geometry and range of test conditions used in early two dimensional film cooling studies as well as the requirements for heat sink models of film cooling. Measurements of film cooling effectiveness computed by various investigators are correlated and compared. The effects of injection velocity and the influences of free stream turbulence and of laminar flows on film cooling effectiveness are discussed. Full coverage film cooling on flat surfaces with different injection systems and the effects of convexity and concavity on turbulent boundary layers are illustrated. Film cooling on over curved surface with and without pressure gradients, the recovery region, and gas turbine measurement are also covered.
