Abstract
The success of supersonic air-breathing propulsion systems will be largely dependent on efficient injection, mixing, and combustion inside the supersonic combustion chamber. Fuel/air mixing enhancement inside the combustion chamber will depend on the strategies used to control the fuel jet penetration and droplet's size, velocity and dispersion. Experimental results on the effect of the gas/liquid mass ratio on the penetration of aerated liquid jet in supersonic cross flow (M=1.5) are presented in this paper. High speed imaging system is used in this study for the visualization of the injection of the aerated liquid jet in high speed cross flow. The results show the effect of jet/cross flow momentum ratio and the gas/liquid mass ratio on the penetration of aerated liquid jet. The data generated in this study can be used for the development of active control strategies to optimize the liquid fuel jet penetration and supersonic fuel/air mixing.
