摘要：

The design, drop size measurement and penetration measurement of the aeroramp liquid injector, an array of angled jets that induce additional vorticity and enhance mixing, were discussed. The liquid injector exhibited good penetration and atomization in comparison to single and simple impinging jet injectors with a weak interaction shock. The maximum shock angle observed near the injector was found to be about 50 deg. The droplet size measurements show effective atomization for the liquid-fuel aeroramp injectors.
