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

The flow feature of transverse hydrogen jet in presence of micro air jets in supersonic flow

“…the geometry of the injection port configuration, the pressure ratio of the jet to crossflow, the number of injection holes and the angle of injection were investigated. Our earlier studies [16][17][18] investigated the influence of the oblique shock on the mixing enhancement, and they showed that the strong axial vortices are generated when the interaction between the oblique shock wave and the jet layer occurs. In our previous studies, the influence of shock wave on the supersonic mixing in scramjet engines are simulated, and we observed that the impinging shock wave diminishes the penetration and enhances the mixing of the injectants irrespective of the molecular weights.…”

“…Although single transverse jet is considered as an efficient model for the injection of fuel in supersonic combustion chambers and scientists have been extensively focused [14][15][16][17][18][19][20][21][22][23][24][25], little works have been performed to reveal the main feature of the interaction between the transverse microjets of two different gases. Moreover, various studies focused on detailed perceptive in the vicinity of flow structure in a single jet-supersonic cross flow [19][20][21][22][23][24][25][26][27] and there is little work on the mixing of the combination of the micro fuel jet with micro air jets.…”

Experimental study of mixing enhancement using pylon in supersonic flow

“…In a computational study by Huang et al [12] the transverse slot injection has been investigated, and it has been observed that high jet to cross flow pressure ratio can increase the injection penetration in the main supersonic flow; the penetration also increases with increase in slot width. A very detailed numerical study by Gerdroodbary et al [13] on the effect of shock on multiple injection system has been studied. It is found out that when the shock generator is just above the first injector, the shock interaction with the second and third injection increases, it results in increased mixing and is also conducive to flame holding.…”

Heat transfer of swirling impinging jets ejected from Nozzles with twisted tapes utilizing CFD technique

“…Computational fluid dynamics, as a research tool, can complete the results of experimental studies by calculating the desired parameters at regions or situations in which experimental work is expensive or impossible [22][23][24][25][26][27].…”
