Increasing the mixing efficiency of fuel jet along combustion chamber is a crucial step for advancement current high-velocity vehicles. In this article, comprehensive computational investigations have been performed to disclose role an annular air on single extruded nozzle located inside chamber. This study has tried offer hydrodynamic insight about flow feature when released from in supersonic cross flow. Computational fluid dynamic used visualization interactions with stream. Effects height mechanism jets are extensively analyzed investigation. Our results show that injection would increase strength circulations, and consequently, improves findings display increases 100% by

Due to sever aerodynamic heating, the protection of forebody scramjet is crucial for hypersonic flight. In present work, a new cooling system proposed and investigated nose cone at Computational fluid dynamic used simulation lateral axial coolant jet released from spike high-velocity condition. The primary goal find optimum location efficient assembly. Influence two jets (Carbon dioxide Helium) on mechanism are fully investigated. For simulation, RANS equations coupled with species transport equation SST turbulence model. Two different configurations (axial disk positions) obtain condition Our results indicate that presence decreases pressure up 33% main body shifts maximum higher angles because deflection air stream. Maximum drops about 50% by injection (C2) angle 55 deg.
