Development of a new cavitation model based on bubble dynamics

This paper presents a numerical approach for a cavitation model that bases on a combination of the Volume-of-fluid technique with a model predicting t he growth and collapse process of bubbles. The cavitation model is applied for the simulation of cavitating nozzle flows and cavitating flow over a NA CA 0015 hydrofoil and showed it's capability to resolve characteristic effe cts of cavitation such as the cyclic formation of the cavitation cloud the formation of the re-entrant jet and the local occurrence of hydrodynamic pr essure peaks due to bubble cloud collapse.
