Emissions from gas turbines are a major issue that could limit the growth of air transport. One important aspect is when the engine is working in off-design conditions (e.g. taxi-ing on the ground) and the flow quality from the compressor is poor and this then affects the processes in the combustor potentially leading to increased NOX and CO. This project will look at the sensitivity of the combustor to inlet conditions and the relationship with emissions and in particular will use a CFD simulation of the compressor coupled to a simulation of the combustor for off-design conditions. The outcomes will allow improved designs that have low emissions both for cruise conditions and other stages of the flight.

燃气轮机的排放是一个主要问题，可能会限制航空运输的增长。一个重要的方面是当发动机在非设计条件下工作时（例如在地面滑行）压缩机的气流质量较差，这会影响燃烧室中的过程，从而可能导致NOX和CO的增加。本项目将研究燃烧室对入口条件的敏感性以及与排放的关系，特别是将使用计算流体动力学模拟压缩机耦合涉及非设计条件下燃烧室的模拟。这些成果将允许改进设计，在巡航条件和飞行的其他阶段都具有低排放。
