Effect of Blockage Inside Holes on Film Cooling Performance on the Suction Side of a Turbine Guide Vane

In order to study the effect of thermal barrier coating deposition inside the film holes of turbine guide vanes on film cooling performance, film effectiveness on the suction side is measured by infrared thermal imaging technology. Film effectiveness is obtained at blockage ratios of 0, 0.2, 0.5, an...
