Abstract: The turbine cavity faces challenges from external mainstream ingestion, mitigated by sealing flow from the compressor side. Despite these efforts, achieving complete sealing remains difficult. This study focuses on introducing ...

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: 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: 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 ...
