Pressure Gradient Effects on Film Cooling [PDF]
Volume 4: Heat Transfer; Electric Power; Industrial and Cogeneration, 1995 Film cooling effectiveness was studied experimentally using a flat plate test facility with a single row of inclined round holes which injected high density, cryogenically cooled air. A pressure distribution representative of the suction side of a gas turbine blade was imposed on the test plate using a top wall contour.
