Abstract: The flows close to a high-pressure turbine endwall are highly three-dimensional and unsteady. These flows increase the aerodynamic loss and augment the heat transfer. In this paper, the unsteady flows and film cooling ...

Abstract: In the serpentine passage of actual rotor blades, the coolant at the inlet of the film hole has an internal crossflow. The internal crossflow significantly influences the film cooling effectiveness of multi-row film holes. ...

Abstract: A laidback fan-shaped hole is commonly used due to its superior lateral film coverage. Its discharge coefficient is significantly influenced by internal crossflow owing to its complex geometrical structure. In this paper, ...
