Abstract： Based on the cavitation model of state equation with the barotropic fluid assumption, and by introducing the filter function to modify the RNG k-ε turbulence model, the NavierStokes equation is solved with SIMPLEC algorithm to simulate both steady and unsteady cavitating flow around a hydrofoil. The calculated pressure distributions on foil section agree well with the experimental results. The periodic and the complex phenomenon of evolution of unsteady cavitating flow is well simulated. The strouhal number coincides with the experiment results. The velocity vector distribution around the foil and the internal flow structure of the cavity are analyzed. The local pressure rise on hydrofoil surface and the breakoff process are mainly caused by the reentrant jet.
