以 CFD 为工具，探索了求取肥大船舶形状因子的新途径。通过比较分析，确定了叠模数值模拟方法中影响形状因子的主要因素。在此基础上，采用相同的网格生成方式和计算参数，对VLCC等10型船进行了形状因子计算，并与国外的试验取值进行了比较。将得到的形状因子用于7万t油船和VLCC的航速预报，与实船测试结果非常吻合，表明该方法可以用于确定肥大船舶的形状因子数值。

Using CFD as the tool, this paper explores a new method to obtain the form factors of full ships. The major influencing parameters on the form factors using the double-body numerical simulation method are determined through comparative analysis. Based on this, the form factors of 10 ship types including VLCC are calculated using the same mesh generation method and computation parameters, and are compared with the foreign experimental results. The obtained form factors are used for the speed prediction of a 70,000t oil tanker and agree well with the actual ship trial result, which proves that this method can be used for predicting form factors of full ships.
