Abstract:The cratered film-cooling hole is regarded as one of the potential
applications with high cooling performance and low cost. This study focuses
on the influence of the protrusion shape for the contoured crater embedded
in the cylindrical hole. Four protrusion shapes, i.e., arc, rectangle,
trapezoid, and triangle, are considered. The cooling effectiveness, flow
structure, and aerodynamic loss for the cratered holes at blowing ratios of
0.5-2.5 are obtained using the numerical method with the Sh… Show more
