Study of ventilated cavity morphology in different gas leakage regime

摘要：

Based on a suite of CFD code, a homogeneous, multiphase, Reynolds averaged Navier Stokes solver coupled with a transport cavitation model and a local linear low-Reynolds-number k e - turbulence model closure was used to simulate the ventilated cavitating flows around a wedge hydrofoil. The gas leakage regimes at the aft of ventilated cavities were investigated. Three gas leakage regimes were observed, and corresponding to each regime, ventilated cavities exhibited a different morphology. The numerical results were compared to corresponding experimental results in qualitative manner. It was found that the general characteristics of the gas leakage regimes and cavity morphology were very reasonably predicted.
