摘要

采用数值计算方法分析超声速气流流过安装凹槽稳定器的燃烧室气动机理和边界层对混合和燃烧的影响。复杂的激波、膨胀波结构和激波边界层的作用有利于气流混合；同时，凹槽内的低速回流区不断和主流气体发生质量动量交换，可以起到点火和火焰稳定的作用。

Abstract

Numerical investigation was conducted to understand the dynamic mechanism and effect of shear layer on the mixing and combustion of supersonic flow in a supersonic combustor with cavities.The complex wave structure including shock wave，expansion wave and the interaction of shock wave with shear layer could effectively and significantly increase mixing; and the mass and momentum exchanges between backflow zones in the cavities and main flow would enhance the ignition and stabilization of combustion.
