Abstract: Converging slot hole is considered as a high-performance film hole with excellent film cooling effectiveness and relatively low aerodynamic loss. Previous studies on converging slot holes mainly focused on the film cooling ...

Abstract: The discharge coefficient of laidback fan-shaped holes on turbine blades under internal crossflow conditions is investigated using experimental and numerical simulation methods. The study is conducted on a linear cascade, ...

Abstract: In the double-wall cooling of turbine blades, coolant migration can lead to uneven flow distribution, which, in severe cases, can cause hot gas intrusion into the film holes, affecting the lifespan of the blade. To mitigate ...

Abstract: This paper focuses on the influences of the discrete-hole shape and layout on the blade endwall film cooling effectiveness. The effect of upstream purge slot injection on the film cooling performance of the discrete hole ...
