中文摘要：
由于多种不确定因素的影响，某些粘性流体力学软件对船体的阻力等水动力性能计算不易获得较有效的结果。文中作者针对粘性流体力学算法（FLUENT软件），探讨了影响船舶水动力学计算的若干因素，对网格生成、离散格式和湍流模型等影响进行了考察。通过一系列的计算、分析，提出了适用于工程实际的改进计算方案和适用于船体阻力计算的参数，据此对文中所研究的单体船阻力进行了改进计算，与试验结果比较表明有较好的符合程度。
英文摘要：
Some of the viscous Computational Fluid Dynamics methods, when applied to hulls ap- pear not easy in giving consistent and agreeable results in resistance and other hydrodynamic per- formance. The authors attempt to find some practical ways by investigating the influential factors such as mesh gridding, choice of discretization schemes and turbulence models which affect the calculation results. Through calculation and analysis, specifically with the CFD code FLUENT, an alternative set of computation parameters for engineering application is suggested. And, the results obtained by applying the proposed method in this paper to mono-hull show better agreement with corresponding model tests.
