Effect of the incident shock wave interacting with transversal jet flow on the mixing and combustion

Effectiveness of jet location on mixing characteristics inside a cavity in supersonic flow

“…[14] has shown that the multiport jet arrays is more effective for mixing in the near-field around the injection location, although no-improvement in far-field compared to the single jet was found. Impinging shock waves on jetted flows from a single port have been shown to improve the mixing [17][18][19]. Mai et al [17] showed that when a shock wave impinges behind an injection slot, the mixing enhances and residence time of the flame is extended.…”

Numerical study of shock wave interaction on transverse jets through multiport injector arrays in supersonic crossflow

“…Although multi transverse injection has been established to be an efficient scheme for supplying fuel in scramjet's combustor and has been greatly studied by researchers [14][15][16][17][18][19], little work has been done to understand the fundamental mechanism of the interaction between the incident shock wave and the transverse micro injections [20,21]. Although several investigations revealed detailed understanding of the near field mean flow structure in a single jet-supersonic cross flow [11,[20][21][22][23], there is little study on mixing of the micro jet under shock wave.…”

The flow structure of the micro jet under effects of shock wave is illustrated in Fig.…”

Experimental Investigation of Impinging Shock – Cavity Interactions with Upstream Transverse Jet Injection

“…Mai et al [10] showed that by having an incident shock impinge downstream of a transverse jet injection location, enhanced mixing of the fuel and air can be achieved leading to increased residence time and more efficient combustion. Employing cavities is another mechanism to improve combustion in scramjets by decelerating the breathing air from supersonic to subsonic speeds for combustion to occur.…”
