Fuel spray and combustion investigation of a prototype engine

点击翻译按钮获取中文摘要

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.
