摘　　要：本文分析了集装箱船和散货船的船舶阻力和标称伴流的性能。采用CFD方法比较网格分布模式和湍流模型等影响因素,并将计算结果与实验值进行了比较。通过分析三种网格方案和两种湍流模型的结果,得到计算标称伴流的最优方案。以某散货船的标称伴流为例进行计算,得到“钩状”伴流。同时,对“钩状”伴流产生的原因进行了较好的分析。预测结果表明:VOF两相流模型的船体阻力计算值与实验值有很好的一致性;集装箱船标称伴流场的轴向伴流、切向伴流与径向伴流的计算值与实验值吻合较好,变化趋势保持一致,验证了本方法设置的可行性。The performance of ship resistance and nominal wakes of a container ship and a bulk carrier were analyzed.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.An optimal scheme for computing the nominal wake was obtained by analyzing the results of three grid schemes and two turbulence models.The nominal wake of a bulk carrier taken as an example was computed and the“hooked”wake was also obtained.At the same time,the cause of the“hooked”wake was fully analyzed.With the experimental results,the predicted results show that the ship resistance calculated by the model of volume of fluid achieves a good agreement.Axial nominal wake,tangential nominal wake and radial wake of the container ship have the same variation trend with the experimental data,and the change trend is consistent,which verifies the feasibility of the method.
