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: Abstract. The swirling flow and the hot spot generated in the aero-engine combustor have significant impacts on the downstream turbine components. This article numerically investigates the influence of the residual swirl ...

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 ...
