Abstract The turbulent characteristics of ducted propeller with pre-swirl stators were simulated numerically and the hydrodynamic performance was analyzed by RNG (ReNormalisation Group) k-ε viscous model. Compared with experimental and potential data, the numerical results are accurate and efficient. Furthermore open water performance of propulsion with different setting angle, section thickness and number of stator blades were predicted numerically. The effect of geometrical parameters on hydrodynamic performance was analyzed.
