Integrated particle separation for high performance turbine cooling

点击翻译按钮获取中文摘要

Research questionHow does solid material (dust, ash, sand) build up in the intricate cooling systems used to implement transpiration cooling. What are the physical mechanisms responsible. How significant is the build up. What mitigations can we apply. How will the answers to these questions differ for future, more advanced systems. Research MethodsAdvanced CFD modelling using commercial codes and bounce / stick models developed by Prof Gillespie's group at Oxford. Tests with hot metal parts at engine scale and engine representative temperatures. The models will be developed to be applicable to double skin cooling systems.
