摘　　要：该文以某散货船为研究对象,分别对其原型与改型船型方案进行了船、桨、舵及其耦合情况下的数值模拟与计算,计算结果包括静水船舶阻力、螺旋桨特性、船桨以及船桨舵耦合情况下船舶自航因子以及船尾流场信息。并对该船自航数值模拟方法和计算策略进行了探索和研究,结果显示原型和改型船数值计算结果与模型试验结果具有较好的一致性。通过该船原型与改型计算结果的比较,分析船体线型对船舶阻力、推进性能以及艉部流场的影响,评价了线型方案的优劣,为今后借助于数值计算方法进行船舶线型优化及船桨舵的优化配合做了有益的尝试。In this article, numerical simulation was investigated for a bulk carrier with two different hull lines of the original hull lines and the modified one. The results of numerical calculations contain resistance in calm water, propeller characteristic, flow field information of the stem and propulsion factors including hull/propeller interaction and hull/propeller/redder intera- ction. The simulation results of both the original hull lines and the modified one are consistent with those of the model tests. Further, the effect of hull lines on ship resistance and propulsion performance was analyzed. Based on the simulation results, the hull lines with better power performance could be obtained. It may be helpful in the optimization of the hull lines and hull/ propeller/redder matching using numerical method in the future.
