...Haiteng Ma; Wei Zeng; Siming Dai; Hongmei Jiang 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 a dilemma in the state...

..., adiabatic cooling effectiveness, and heat transfer coefficient (HTC). The results showed that the adiabatic cooling effectiveness could reach 0.65 with a blowing ratio lower than 0.5. Meanwhile, the heat transfer coefficient ratio (h f /h 0 ) of transpiration cooling was close to 1 with a small blowing...

... significantly lower amounts of coolant. Contours of adiabatic cooling effectiveness on the shroud underside surface (platform cooling) The cooling effectiveness contours on the shroud underside surface are presented in Fig. 16 . In comparison with the rail-cooling test case, the coolant distribution...
