Integrated particle separation for high performance turbine cooling

研究问题：固体物质（灰尘、灰、沙）是如何在用于蒸腾冷却的复杂冷却系统中积聚的？物理机制是什么？建立的意义有多大？我们可以采取哪些缓解措施。对于未来更先进的系统，这些问题的答案会有什么不同？研究方法利用商业代码和牛津大学吉莱斯皮教授团队开发的弹跳/粘滞模型进行高级CFD建模。在发动机规模和发动机代表温度下用热金属部件进行试验。这些模型将被开发成适用于双表皮冷却系统。

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.
