针对传统海洋工程水动力分析软件不能耦合叶片气动载荷、风波载荷以及涡尾迹效应，建立以OC3-Hywind单柱式平台为基础的NREL-5MW海上风力机整机模型,运用计算流体力学软件STAR-CCM+,结合流体体积函数方法与动态流体相互作用模型实现气动-水动-系泊全耦合动力学分析。研究发现：所采用的计算流体力学方法能够有效捕获塔影效应对转子气动性能造成的影响,且气动与水动响应结果较单部件计算结果均在合理范围内；流场可视化结果表明在风波联合作用下,涡管上的附着涡不断从涡管表面脱落,并与塔架后方尾涡相互作用,加剧了FOWT流场的复杂性。研究结果为单柱式海上漂浮风力机全耦合分析提供参考。

Aiming at the traditional ocean engineering hydrodynamic analysis software which cannot couple blade aerodynamic load, wind wave load and vortex wake effect, the NREL-5MW offshore wind turbine model based on the OC3-Hywind single-column platform is established, and the computational fluid dynamics (CFD) software STAR-CCM+ is used to combine the fluid volume function method with the dynamic fluid interaction model to realize the fully coupled dynamics analysis of the aerodynamic-hydrodynamic-mooring. It is found that: the adopted computational fluid dynamics method can effectively capture the influence of tower shadow effect on the aerodynamic performance of the rotor, and the aerodynamic and hydrodynamic response results are within a reasonable range compared with the results of the single-part calculations; the results of the flow field visualization show that under the combined effect of wind and wind waves, the attached vortices on the vortex tube are continuously detached from the surface of the vortex tube and interact with the tail vortex at the rear of the tower, which exacerbates the complexity of the flow field of the FOWT. The results provide a reference for the full-coupling analysis of a single-column offshore floating wind turbine.
