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.

研究问题固体物质（灰尘、灰烬、沙子）是如何在用于实现蒸发冷却的复杂冷却系统中积聚的。什么是物理机制负责。建设有多重要。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何不同。 研究方法先进的CFD建模使用商业代码和反弹/坚持由吉莱斯皮教授的小组在牛津大学开发的模型。在发动机规模和发动机代表性温度下使用热金属部件进行试验。该模型将被开发为适用于双层皮冷却系统。
