This paper discusses the application of the CFD to transitional and cavitating flow around marine propellers. Especially the emphasis is put on the adaption of the 3 equations turbulence model for the non-cavitating flow and tip vortex resolution on cavitating flow. This research finds 3 equations turbulence model is effective for prediction of the propeller open characteristics in the wide range of Reynolds number. Next, numerical simulation of cavitating flow with tip vortex resolution is validated. Furthermore, simple cavitation erosion index is applied and shows good agreement with experimental results. Finally, effect of tip vortex resolution on the pressure fluctuation at the top of the propeller is discussed.
