Abstract: The high-speed relative motion between the casing and turbine blade tip significantly complicates the flow field distribution near the blade tip and greatly increases the difficulty of flow field measurement. In this paper, ...

Abstract: The overtipleakage (OTL) flow characteristics for a typical squealer tip of a highpressure turbine blade, which consists of subsonic and transonic flow, have been numerically investigated in the present study, in comparison ...

Abstract: Modern high-pressure turbine blades operate at high-speed conditions. The over-tip-leakage (OTL) flow can be high-subsonic or even transonic. From the consideration of problem simplification and cost reduction, the OTL ...

Abstract: Film cooling, as a key technology to ensure turbine survival in new generation gas turbines, has been studied profusely in subsonic flows. But in transonic flow, the determination of adiabatic cooling effectiveness faces ...
