Abstract

This work deals with a numerical simulation of the effect of injection pressure fluctuations on the cavitation processes in injection nozzles. The numerical approach is based on predicting the growth and collapse of bubbles in combination with a modified Volume-of-Fluid technique (VOF). A k-omega model is applied for turbulence modeling. Calculations confirm that there exists phase shift among the time history of the injection pressure, the transient velocity, and the cavitation process.
