Adiabatic and Overall Effectiveness for a Fully Cooled Turbine Vane
Volume 3B: Heat Transfer, 2013Adiabatic and overall effectiveness data were measured for a fully cooled, scaled up turbine vane model in a low speed linear cascade with a chord-exit Reynolds number of 700,000. The overall effectiveness is a measure of the external surface temperature relative to the mainstream temperature and the inlet coolant temperature, and consequently is a ...

Numerical Investigation on Overall Cooling Effectiveness of Narrow-Channel Double-Wall Cooling
ASME Journal of Heat and Mass TransferAbstract 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 the negative influence of coolant migration, this study proposes a novel double-wall system called the ...

The cooling system is required to ensure gas turbine can work at high temperature, which has exceeded the material limitation. An endwall cooling test rig was built up to conduct the endwall cooling research. A detailed work was done for analyzing characteristics of endwall heat transfer and discussing the multi-parameter influence mechanism of overall

Film cooling experiments were run at the high speed cascade wind tunnel of the University of the Federal Armed Forces Munich. The investigations were carried out with a linear cascade of highly loaded turbine blades. The main targets of the tests were to assess the film cooling effectiveness and the heat transfer in zones with main flow separation ...

Abstract The overall cooling effectiveness, which represents the distribution of dimensionless temperature on gas turbines surface, is an important parameter for conjugate heat transfer analysis of gas turbines. Generally, it is difficult to measure the overall cooling effectiveness in engine condition.

Adiabatic and overall effectiveness levels were measured in a closed loop linear test section using an inlet Reynolds number of 120,000 for an airfoil model at its designed inlet angle of −30.1°. Two models were used in the study — one made of a low thermal conductivity foam, and one of a higher thermal conductivity material which allowed for the Biot ...
