Abstract
Practical injectors typically involve high speed flows and large static pressure variation along the liquid stream before it exits the injector. As a result, the phenomenon of cavitation and the formation of a liquid-vapor mixture within the nozzle is always a possibility. The effects of cavitation may be beneficial (improved atomization) or undesirable (damage to injector walls due to violent cavitation bubble collapse); but regardless of the nature of effects, in both cases it is important to characterize cavitation within injector nozzles and understand its dynamics. Previous work on the diagnostics of cavitation within injectors is reviewed here.
