Future gas turbine combustion chambers and turbine blades require better cooling techniques to cope with the continual rise in operating temperatures with each new engine model. One technique that has been extensively investigated is that of transpiration cooling, for both combustion chambers (1–5) and turbine blades (6–9).

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 ...

Journal of Thermal Science and Engineering Apllications
To enhance the cooling deficiency that occurs in a baseline endwall using axially-arranged cooling holes, this paper proposes a new locally-enhanced hole layout using curtain cooling and fan-shaped film holes being arranged on iso-Mach lines.

Volume 5A: Heat Transfer, 2015
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

Journal of Turbomachinery, 2012
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 ...

Volume 5C: Heat Transfer, 2016
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 ...

Experimental investigations on overall cooling effect of ribbed channel with air bleeds
International Journal of Heat and Mass Transfer, 2012Abstract An experimental investigation on overall heat transfer performance of a rectangular channel, in which one wall has periodically placed oblique ribs to enhance heat exchange and cylindrical film holes to bleed cooling air, has been carried out in a hot wind tunnel at different mainstream temperatures, hot mainstream Reynolds numbers, coolant ...
