Tiny Cavitation Bubbles Enhance Energy Conversion in Fuel Injectors’ Jets
Department of Energy, Office of ScienceScientists have a limited understanding of the effects of cavitation in microscopic devices. In this research, scientists took high-speed images of microscale cavitating fuel jets to understand the motion of liquid jets from high-pressure fuel injectors like those used in vehicle engines. Analysis of the results showed that cavitation enhances the energy conversion efficiency of the fuel injection.
