中文摘要：

为了研究某载人潜水器支持船舶的水动力性能,以该船模型为研究对象,应用数值模拟软件STAR-CCM＋对其进行快速性能预报与流场分析,并与拖曳水池试验值进行对比.通过阻力性能、船舶艏艉波系、船身流线等与试验值的比较,数值模拟计算结果和模型试验结果具有较好的一致性.结果表明：数值预报精度满足工程应用的需要,较好地反映了船舶阻力性能与其周围流场的真实信息,为该船舶舭龙骨、螺旋桨的安装及船体型线的改进提供借鉴和参考.

英文摘要：

In order to study the hydrodynamic performance of the manned- submersible-supported ship,a model on the ship was taken as the research object,the numerical simulation software STAR-CCM＋ was applied to predict the rapidity of the vessel and analyze flow field, and the test results of towing tank were adopted for comparison. By comparing resistance performance,bow and stern wave systems,streamline around hull with the test values, it was found that the results of numerical simulation calculation keep in good consistency with the test results. The results show that the accuracy of the numerical simulation prediction meets the need of engineering application and properly reflects the real information of the ship resistance performance and surrounding flow field. Such results provide ref-erences and guidance for installation of bilge keel and propellers as well as the improvement of hull lines.
