Abstract
In order to analyze the performance of ship resistance and nominal wake of container ship and bulk carrier, the method of CFD was used to compare the influence factors such as the distribution pattern of grids and turbulence models, and the calculation results were compared with experimental values. The predicted results show that the ship resistance calculated by the model of Volume of Fluid achieves a good agreement with experimental data. An optimal scheme for computing the nominal wake was got by analyzing the results of three grid schemes and two turbulence models. The container ship's axial nominal wake, tangential nominal wake and radial wake has the same variation trend with the experimental data, so it validates the feasibility of this method set in this paper. Thenominal wake of a bulk carrier took as an example was computed and the "hooked" wake was also got very well. At the same time, the cause of the "hooked" wake was got a good analysis.
