【 摘 要 】

The cavitation on the lip of a flushed water-jet inlet has been simulated with a transient RANS model and the results has been validated against experiments. The k-ω SST turbulence model has been adopted together with the cavitation correction proposed by Reboud. The defined setup shows promising results and the vortex shedding has been qualitatively predicted. Moreover, the importance of the sufficient spatial resolution to capture the cavity closure and its extension has been studied and proved to be crucial.
