【Abstract】 In order to accurately predict the ship resistance, a 30 000 ton teaching practice ship is selected as the research object. Based on CFD,the ship resistance at different speeds in still water is numerically simulated, and a three-dimensional hull model is established. The grid is processed by local encryption and standard The VOF method is used to track the free surface of K-ε turbulence model. The results are compared with the ship model test data. The results show that the method has the advantages of fast calculation speed, low cost and high prediction accuracy, which is of great engineering significance.更多还原
