摘　　要：基于CFD软件STAR-CCM+,以西陵峡双体游船为研究对象,对该船在一定缩尺比下的模型自航数值模拟计算进行研究,将数值计算结果与已有试验结果对比,验证数值计算的准确性。在此基础上,将西陵峡游船尾部的歪尾线型改为直尾线型重新建模,采用同样的方法对直尾船完成自航数值模拟计算。对比两种尾部线型船的计算结果,分析自航因子,结果表明,该船型采用歪尾的推进效率高于采用直尾的推进效率。Based on the CFD software STAR-CCM+,taking the Xiling Gorge cruise ship as the research object,the numerical simulation of the ship’s model self-propulsion under a certain scale ratio was studied.The calculation results were compared with existing experimental ones to verify the accuracy of the numerical metthod.On this basis,the skewed stern line of the Xiling Gorge cruise ship was changed to a straight stern line for re-modeling,carrying out the self-propelled calculation by using the same method.Comparing the calculation results of two types of stern type ships,the self-propulsion factor was analyzed.It was shown that the propulsion efficiency of this ship type using skewed stern is higher than that using straight stern.
