Applying EHD effects on cavitation flow in a nozzle of fuel injector, A novel method for fuel atomization enhancement

Various cavitation regimes which occur in a nozzle of fuelinjector play a dominant role in the fuel spray atomizationprocess and the subsequent spray combustion quality andreduction of emissions. In this paper, the effect ofelectrowetting phenomenon on cavitation flow in nozzle offuel injector and subsequent atomization characteristics, inthe presence of nozzle wall material modification and usingaccessible range of DC voltages of engine supplementaryelectronic system, was numerically investigated.
