| 摘 要： | 为了考察超声速混合层混合、燃烧流场特性，并探索其被动增强方法，利用高速纹影、自发辐射成像和平面激光诱导荧光(PLIF)技术对压力匹配条件下的超声速混合层在不同隔板构型下的流场特性进行研究.结果表明:相对于对混合层混合的影响，凹腔对燃烧的影响明显受到抑制；尾部交错结构隔板促进混合层流向涡的产生，大大提高了混合层内燃烧强度.

| Abstract: | To investigate the mixing, combustion characteristic and passive mixing enhancement methods of supersonic mixing layer, pressure matched supersonic mixing layer with different geometric configurations was explored using high speed schlieren photographs, spontaneous emission imaging and planar laser induced fluorescence(PLIF) imaging．Results showed that, the influence of cavity on supersonic mixing layers was repressive under combustion condition. Splitters with sawtooth trail induced large scale streamwise vortexes and great influence of combustion enhancement in supersonic mixing layer. |

| Keywords: | supersonic mixing layer spontaneous emission OH PLIF(hydroxide radical planar laser induced fluorescence) combustion steamwise vortex |
