Angled and tapered injectors have been subjected to detonation fronts at high-pressure conditions and analyzed using high-speed videos. A total of 846 tests were conducted to characterize refill times and back-flow distances of nine different injector geometries. Water was used as the working fluid, and ethylene–oxygen was utilized to produce the detonation wave. Experiments were performed at two different vessel pressure settings (approximately 4 and 6.8 atm). Refill time data were normalized to obtain a general trend for transient response of liquid injectors to provide a predictive mechanism for injector designers.

在高工作压力下，成角度的和锥形的液体喷射器对通过的爆轰波前的响应

倾斜和锥形喷油嘴在高压条件下经受了爆轰前沿的考验，并使用高速视频进行了分析。总共进行了846次测试，以表征9种不同喷射器几何形状的加注时间和回流距离。水被用作工作流体，而乙烯-氧气被用于产生爆炸波。实验是在两种不同的容器压力设置（约4和6.8大气压）下进行的。对加注时间数据进行了归一化，以获得液体喷射器瞬态响应的总体趋势，从而为喷射器设计人员提供了一种预测机制。
