中文摘要：[目的]为了研究船舶在斜航条件下的粘性绕流场,为研究船舶操纵性提供相关依据,[方法]采用商用软件STRA-CCM+,选取SST k-ω湍流模型,对KVLCC2模型在不同漂角条件下的水动力性能、船体流场进行预报。观察船模在不同漂角下的压力分布情况,并对船底涡系脱落及船体表面约束流线进行观测。[结果]结果表明,数值模拟在预报船舶横向力和转艏力矩以及船身表面的压力分布时满足工程应用的要求。[结论]所得结论对研究船舶斜航条件下的流动分离现象具有一定的参考价值。

外文摘要：[Objectives]This paper is intended to study the viscous flow field around a ship under oblique conditions and provide a research basis for ship maneuverability.[Methods]Using commercial software STRA-CCM+,the SST k-ω turbulence model is selected to predict the hydrodynamic performance of the KVLCC2 model at different drift angles,and predict the hull flow field. The pressure distribution of the ship model at different drift angles is observed and the vortex shedding of the ship's hull and constraint streamlines on the hull's surface are also observed.[Results]The results show that numerical simulation can satisfy the demands of engineering application in the prediction of the lateral force,yaw moment and hull surface pressure distribution of a ship.[Conclusions]The research results of this paper can provide valuable references for the study of the flow separation phenomenon under oblique conditions.
