This actual extension of our previous work demonstrates the strong interaction of cavitation inside injection nozzles with the external jet flow. Due to the high sensitivity of cavitation on the imposed initial and boundary conditions, simulations with restriction to the internal nozzle flow are qualitatively and quantitatively incorrect. Results of this very first simulations indicate the potential of cavitation for enhancement of atomization and spray formation.
