Experimental investigation into unsteady effects on film cooling
Significance of output:
This paper shows the fundamentally unsteady nature of turbine film-cooling flows, which is an area where aero-engine manufacturers require constant improvements. This is because increasingly higher turbine gas temperatures are needed in order to raise aero-engine performance which means that cooling effectiveness and efficiency is of major importance to aero-engine manufacturers. This work formed part of an EPSRC/Rolls-Royce (SAMULET EP/G035245/1) supported PhD project. The results show large-scale unsteady flows which exist in turbine cooling flows, and these can influence heat-transfer and therefore performance degradation.
