In this paper, the Mixture multiphase flow model and the Schnerr-Sauer cavitation model are used to simulate the tip vortex cavitation of the propeller and then to predict the sound pressure level of the propeller. The structured and unstructured grids are adopted in stationary domain and rotating domain, respectively. The moving reference frame model is used in the rotating domain. The open water characteristics of the propeller are calculated by the SST k-ω turbulence model and the isosurface of vorticity magnitude is clearly presented. The results of the calculation are compared with the non-cavitating condition. It shows that the efficiency of the propeller is reduced when the tip vortex cavitation appears. The tip vortex cavitation will lead to increases both in the overall sound pressure in time histories and in the sound pressure level in the frequency domain.
