A large-eddy simulation (LES) with one-equation dynamic (OD) model was performed for turbulent cavitating flows around a Clark-Y 11.7% hydrofoil. Our results for time-averaged lift and drag were compared with experimental and computational data in previous studies. In terms of the breakdown properties, our method improved the reproductivity of the experimental evidence. We investigate turbulent structures of these flows, and we confirmed an importance of resolving near the surface region in order to reproduce the breakdown properties.
