摘要：

A liquid injection scheme in a supersonic crossflow, namely transverse liquid injection accompanied with a gas jet, is proposed and investigated experimentally and numerically. High-speed photography was adopted to capture the jet spray in the experimental work; while a discrete phase model was utilized to simulate the liquid jet penetration and gas-liquid interaction in the numerical study. The differences between transverse liquid injection with and without an accompanied gas jet were analyzed. The effects of an accompanied gas jet were determined. Both the experimental and computational results indicate that an accompanied gas jet can significantly enhance liquid jet penetration. Simulation results also indicate that gas injection would cause additional total pressure losses.
