【 摘 要 】

A compressible, two-phase, one-fluid solver has been developed to investigate the behaviour of cavitation models. The model is based on a transport equation for the volume fraction of gas. Numerical simulations are performed on a cavitating Venturi flow where a selfsustained cavitation pocket develops. The sheet dynamics involving traveling pressure waves is investigated.
