In this paper, a numerical study has been conducted to investigate the evolution of a ship propeller tip vortex over large distance using Reynolds-averaged Navier Stokes (RANS) CFD method. In order to reduce numerical dissipation in tracking the tip vortex, a unique hybrid mesh structure was designed and a vorticity confinement method is also introduced to further enhance the high resolution of the tip vortex.
