A comparative study of cavitation models in a Venturi flow
Résumé
This paper presents a numerical study of an aperiodic cavitation pocket developing in a Venturi flow. The mass transfer between phases is driven by a void ratio transport equation model. A new free-parameter closure relation is proposed and compared with other formulations. The re-entrant jet development, void ratio profiles and pressure fluctuations are analysed to discern results accuracy. Comparisons with available experimental data are done and good agreement is achieved.
