Modeling and computation of unsteady cavitation flows in injection nozzles

This paper deals with the numerical simulation of cavitation phenomena inside injector nozzles. The numerical approach combines the Volume-of-Fluid technique (VOF) with a model predicting the growth and collapse of bubbles. To model the turbulence effect a k–ω model is introduced for the two-phase flow. Calculations show that the numerical method is able to reproduce complex cavitation phenomena as observed in injection nozzle experiments.
