Abstract: This paper presents an experimental investigation of the rectangular diffusion hole. The effects of rectangular aspect ratio and lateral diffusion angle on film-cooling effectiveness were studied at a low-speed flat-plate ...

Abstract: This paper presents a method to improve the filmcooling effectiveness of cylindrical holes. A short crescentshaped block is placed at the downstream of a cylindrical cooling hole. The block shape is defined by a number of ...

Abstract: Film-cooling effectiveness of rectangular diffusion holes under an inclination angle α = 45 deg, an orientation angle β = 45 deg, and a length-to-diameter ratio of L/D = 8.5 were, respectively, examined in a flat-plate ...
