The proposed project aims at improving the performance of an aerospace prototype engine by an experimental approach and to simultaneously develop CFD tools that will be useful to the R&D pursued by the industrial partner. To achieve those broad technical objectives, experiments will be pursued to get a better understanding of the phenomena at play during the fuel-air mixture formation and its impact on combustion and performances. In parallel to the experimental works, fuel spray models will be developed and calibrated over representative range of conditions.The results will greatly benefit the industrial partner, as the experimental research will allow evaluating the engine performances using a parametric study approach. The results could help identify engine limitations for future design and improvement. Another usefulness of the engine performance parametric study is that the result would enhance P&WC in-house predictive models over a wide range of conditions. On the numerical side, the CFD model calibration developed will be used by the design team of the industrial partner and will complement their CFD model development effort.The expertise gained by the HQP in numerical and experimental methods as part of this project will make them very attractive from the industrial perspective, as the aerospace industry (as well as other industries such as the automotive industry, for example) uses both approaches in product development.

该项目旨在通过实验方法改善航空航天原型发动机的性能，同时开发对工业合作伙伴进行研发有用的CFD工具。为了实现这些广泛的技术目标，将进行实验，以更好地了解燃料-空气混合物形成过程中的现象及其对燃烧和性能的影响。与实验工作同时进行的还有燃油喷雾模型的开发和标定，其结果将使工业合作伙伴受益匪浅，因为实验研究将允许使用参数研究方法评估发动机性能。研究结果有助于确定发动机的局限性，以便将来进行设计和改进。发动机性能参数研究的另一个有用之处是，其结果将在广泛的条件下增强P&WC内部预测模型。在数值方面，工业合作伙伴的设计团队将使用开发的CFD模型校准，并将补充其CFD模型开发工作。HQP在本项目中获得的数值和实验方法方面的专业知识将使其从工业角度来看非常有吸引力，因为航空航天工业（以及其他行业，例如汽车行业）在产品开发中使用这两种方法。
