Abstract
Cavities can easily form in the low pressure zone on the surface of a hydrofoil moving under water. Detached-eddy simulation (DES) was applied to unsteady cavitating flows over a hydrofoil. The formation, development, collapse and detachment of the cavities were simulated. Consequent variations in lift and drag on the hydrofoil were obtained. Simulation results showed that cavitating flow has significant periodic characteristics, and lift and drag on the hydrofoil vary synchronously. Comparisons with experimental data showed that cavitating flows can be predicted well by the method discussed.
