[Abstract]:This paper introduces the basic principle of plasma enhanced combustion, summarizes three ways of plasma enhanced combustion, namely, thermal enhancement, dynamic enhancement and transport enhancement, and summarizes the latest representative results in the application verification, action mechanism and numerical simulation of plasma enhanced combustion in the world, especially in China. Four research directions of plasma enhanced combustion are put forward, which are plasma enhanced combustion mechanism, multi-field coupling modeling and simulation, test and diagnosis, and other scientific and technical problems in the application of plasma enhanced combustion in aero-engine. At the same time, some suggestions for carrying out the research work in these four aspects are put forward, mainly to quantitatively study the three effects of plasma ignition and combustion. The relationship between each effect and ignition characteristics and combustion characteristics is established respectively. The detailed dynamic model of plasma enhanced combustion is established, the new testing technology of plasma enhanced combustion is developed by using advanced test and diagnosis equipment, and the matching problem of plasma ignition and combustion assistance applied to different types of engine combustion chambers is considered, especially the miniaturization and lightweight of plasma power supply.
