摘要：

对超声速燃烧不稳定性这一新兴领域的研究进行了综合评述，并对未来研究进行了展望。首先分析了超声速燃烧不稳定性现象的基本特性及其影响因素；随后讨论了超声速燃烧不稳定性的多种机理；接着概括了基于上述机理的超声速燃烧不稳定性建模；最后对超声速燃烧不稳定性还需重点研究的方向给出建议。综述表明，超声速燃烧不稳定性的现象、机理和建模都还需持续开展研究，特别需要关注的是燃烧室构型布局和燃料喷注方式对超燃冲压发动机燃烧不稳定性现象的影响，在超声速混合层和射流等典型流动中更深入探索超声速燃烧不稳定性机理，基于超声速燃烧系统的湍流时空演化特性进一步发展超声速燃烧不稳定性模型。

Abstract:

The present paper conducts a review of the research on the new field “supersonic combustion instability”. Firstly, the basic properties and affecting factors of the phenomena of the supersonic combustion instability are analyzed; then, several kinds of mechanisms of the supersonic combustion instability are discussed; thirdly, the modeling of the supersonic combustion instability based on the above mechanisms is summarized; finally, the directions of the supersonic combustion instability that need essential concern are suggested. The review demonstrates that the phenomenon, mechanisms and modeling of the supersonic combustion instability all need continuous researches.The future researches may focus on the effects of the combustion chamber configuration and fueling scheme on the phenomena of the scramjet combustion instability, further explore the mechanisms of the supersonic combustion instability in the canonical flows such as supersonic mixing layers and jets, and further develop models of the supersonic combustion instability based on spatial and temporal evolution of the turbulent characteristics of the supersonic combustion systems.

Key words: Combustion instability, Supersonic combustion, Scramjet engine, Flow instability, Thermo acoustic instability
