| Popis: | 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. |
