摘　　要：针对CFD在不同计算模型下计算结果的精度问题,对1艘标准船模建立不同网格密度、不同Y+、以及不同湍流模型下的计算模型,得到不同维度下的计算结果,复合航次试验结果表明,网格密度、近壁面Y+、以及湍流模型对计算结果有较大影响,k-ε、k-ω,以及SST湍流模型的最大误差分别为2.41%、5.36%和3.65%,k-ε和SST湍流模型的部分结果与试验结果贴合度极高,说表明通过合理设置仿真模型,可以有效提高计算精度;通过复合航次试验,能够有效降低试验误差。The error of CFD simulations with different calculation models was studied.Taking a standard ship model as the research object,the calculation models with different grid density,different Y+and different turbulence models were established to calculate the multi-dimensional results of the repeat-run towing tank resistance tests.The test results showed that the grid density,near-wall Y+and turbulence model have significant influence on the simulation results,the max error of the k-ε、k-ωand SST turbulence model were 2.41%、5.36%and 3.65%,respectively.Some of the results are in good agreement with the experimental results,showing that reasonable settings of the simulation models will make higher calculation accuracy,and the test error can be effectively reduced through the repeat-run tests.
