低频振荡燃烧研究综述

SUMMARIZATION OF LOW-FREQUENCY OSCILLATORY COMBUSTION STUDY

总结了影响涡扇发动机加力燃烧室和冲压发动机燃烧室的结构及运转因素，综述了有关振荡燃烧机理研究的一些结果以及几项很有意义的主动控制技术。结论是，目前国内外所进行的低频振荡燃烧的机理、预测及控制工作，尚处于探索阶段。

he paper summarizes the structure and operation factors that influence the combustion instability in turbofan augmentor and ramjet, and summarizes some explanation about the lowfrequency oscillatory combustion mechanism,and a few act-control methods. The conclusion of the paper is that the work done in the world about the mechanism, prediction and control of low-frequencyoscillatory combustion in turbofan augmentor and ramjet is only in developing stage.
