Abstract

We present an Eulerian three-component two-phase model for the large-eddy simulation (LES) of the cavitating flow within liquid-fuel injectors and the primary atomization of injected fuel jets. The model is applied to a generic nozzle and jet flow at different cavitation numbers and Reynolds numbers. We find that the LES correctly reproduce experimentally observed cavitation effects. Cavitation collapse events near the exit plane of the nozzle increase the turbulence level, perturb the liquid-gas interface, and enhance the jet breakup.
