Impact of machining deviation on cooling effect of dustpan-shaped film hole
The impact of two kinds of typical machining deviation in actual production process on the cooling effect of dustpan-shaped film holes was studied by numerical simulation.And compared with that of the elliptic film hole and the theoretical dustpan-shaped film hole.The results show that the cooling effect of the dustpan-shaped film hole is higher than that of the elliptic film hole with the same hole diameter and the same cooling air flow.The machining deviation will cause the cooling effect of the dustpan-shaped film hole to decrease greatly.The results show some reference to the actual film hole machining and blade acceptance of turbine cooling blades.
