项目摘要

The objective of this project is to experimentally investigate the interaction between lean turbulent swirling flames being relevant for aero engines and effusion cooling of combustor walls. The research focus is on the impact of effusion cooling upon local thermochemical states, reaction rates and primary formation of carbon monoxide as important pollutant species. Demands for aero engines are increasing, and result from the agreement targets of ACARE2020 or the Flightpath 2050. These demands enforce a replacement of rich-quench-lean combustion by lean combustion concepts, due to their potential for much decreased formation of nitric oxides. As a drawback, the amount of available cooling air decreases and reaction zones are shifted closer to the combustor walls. As a consequence, the thermal load at the walls is strongly increased which is intensified additionally by higher cooling air temperatures due to higher pressure ratios as needed to improve fuel consumption. Cooling air streams are not only highly important for the thermal management, but influence as well combustion chemistry. Whereas efficient cooling concepts have been investigated broadly in the past, the impact of cooling air flows upon local thermochemical states, reaction rates and pollutant formation has hardly been investigated although these issues are highly relevant for meeting future environmental targets. This project aims to focus on these challenging issues. For this purpose laser diagnostics are applied to a pressurized combustor where important features of gas turbine combustion are mimicked. Experimental results will serve for an improved understanding of the interlinked physical and chemical processes and unique experimental data will support validation of numerical combustion modelling.
本项目的目的是通过实验研究与航空发动机相关的稀薄湍流旋流火焰与燃烧室壁面喷雾冷却之间的相互作用。重点研究了渗流冷却对重要污染物一氧化碳的局部热化学状态、反应速率和初级生成的影响。对航空发动机的需求正在增加,这是ACARE2020或FlightPath 2050协议目标的结果。这些要求要求用稀薄燃烧概念取代浓冷稀薄燃烧,因为它们有可能大大减少一氧化氮的形成。作为一个缺点,可用冷却空气量减少,反应区向燃烧室壁移得更近。结果是,墙体的热负荷大大增加,而由于需要更高的压力比来改善燃料消耗,更高的冷却空气温度进一步加强了墙体的热负荷。冷却气流不仅对热管理非常重要,而且对燃烧化学也有很大的影响。虽然高效冷却的概念在过去已经被广泛研究,但冷却气流对局部热化学状态、反应速率和污染物形成的影响几乎没有被研究过,尽管这些问题与实现未来的环境目标高度相关。该项目旨在关注这些具有挑战性的问题。为此,激光诊断应用于加压燃烧室,其中模拟了燃气轮机燃烧的重要特征。实验结果将有助于更好地理解相互关联的物理和化学过程,独特的实验数据将支持数值燃烧模型的验证。
