Abstract
Studies on the cooling effectiveness distribution between scalelike laminated plate cooling duct and routine round film hole with Numerical Investigation show that the inner duct structure of the scalelike laminated plate can even the temperature and velocity on the exit of the film hole and the arrangement of film holes can even the coverage of the film on the wall surface to lower the decline rate of the wall surface temperature; The scalelike inner duct structure can cause turbulence in the cooling air when they meet at the intersection, hence benefit the convection exchange inside the mental surface; The scalelike laminated plate can also twice the cooling effectiveness of the routine round film hole.
