combustion characteristic and passive mixingenhancement methods of supersonic mixing layer
pressure matched supersonic mixing layer with different geometric configurations was explored using highspeed 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 largescale streamwise vortexes and great influence of combustion enhancement in supersonic mixing layer.
