A partial sheet cavitation model is developed and implemented within a 3D BEM code in order to estimate the hydrodynamics forces and performance of a propeller or rudder operating in an unsteady flow. The model proposes a relationship between the sheet cavitation geometry and the pressure distribution in subcavitating conditions. The model is validated for 2D pressures and 3D cavity length distributions. For steady flow conditions, the method is validated for lift and drag of a 3D hydrofoil. For unsteady flow, applications of propellers and rudders demonstrates the performance of the model.
