Three-dimension Numerical Simulation of A Supersonic Flow with Transverse Hydrogen Jet

Three-dimension numerical simulation of a supersonic flow with transverse hydrogen jetis performed using ASUMDV scheme and k-ω SST two-equation turbulence model with Wilcox compressibility correction. The numerical results are compared to the experimental data and the good agreements indicate that the adopted numerical method is reliable. The flow and mixing characteristics of the flowfield are analyzed in detail. It is found that: the complicated vortex system and mixing process are well captured by the numerical scheme and turbulence model; the mixing process between air and hydrogen is mainly controlled by a counter-rotating streamwise vortex pair generated by interaction between mainstream and jet, which indicates that increasing the strength of the streamwise vortex is an effective method to enhance the mixing rate between air and hydrogen; in the jet wake region, the heat release is relatively higher near the wall, so the penetration height of jet should large enough in practical application to avoid too high heat flux on the wall.
