CFD Modeling of Propeller Tip Vortex over Large Distances

Artikel i vetenskaplig tidskrift, 2014

In this paper, a numerical study has been conducted to investigate the evolution of a ship propeller tip vortex over a large distance by 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 was also introduced to further enhance the high resolution of the tip vortex.
