摘要
Abstract
Wetook a two-dimensional hydrofoil calculation modelas the research object, and adopted the method of numerical simulation. The movementof the hydrofoil cavity in the cavitation process was obtained through the numerical simulation study on diff erent cavitation models and turbulence models. The result showed: In different types of cavit at ion models, the cavitation process of this hydrofoil included the generation, development, fall-off, and burstof vacuoles, and the process showed obvious periodicity. The simulation resultof S-S cavitat ion model was consistent w ith The act ual movement. The S-S cavitation model can well simulate the flow around a hydrofoil in the cavitat ion process.关键词
