Abstract

Based on Homogeneous Equilibrium Model combined with full cavitation model, the cavitation flow inside a single-hole diesel nozzle is simulated. In order to analyse the effect of the fuel temperature increase on the characteristics of the internal cavitating flow, the inception and development of cavitation inside the diesel nozzle were analysed separately. Furthermore, the effect on the outlet velocity was also discussed. The computational results show that the temperature rising had significant effects on the cavitation flow inside a diesel nozzle. With the rising of fuel temperature, the cavitation phenomenon inside the nozzle appeared earlier, the transition to supercavitation was accelerated and the outlet velocity increased.
