摘要 A finite volume, multiphase solver in the framework of OpenFOAM is used to calculate the flow field of the cavitating flow over the Clark-Y hydrofoil. This solver uses Transport Based Equation Model (TEM) to solve the liquid volume fraction, and utilizes volume of fluid (VOF) technique to predict the interface between liquid and vapor phases. The simulation is designed to study the cavitation shedding and different fluid characteristics in the cloud cavitation regime when adopting two different Large Eddy Simulation (LES) models, namely, one equation eddy viscosity (oneEqEddy) model and Smagorinsky model. It is shown that these two models can be used to study the cavitation shedding dynamics and predict the velocity profiles.
