摘　　要：基于非稳态致动线模型求解三维N-S方程的方法,对OC3项目Hywindspar基础的浮式风机进行其气动-水动-锚泊系统的耦合动力数值分析.计算分析分为两个部分:将上部风轮受到的气动推力简化为定常力(力矩),作用于平台;风机叶片简化为致动线模型耦合到CFD求解器naoe-FOAM-SJTU中,进行浮式风机系统的耦合动力分析.最后,对比分析两种情况下浮式风机系统的气动以及水动力响应.分析结果显示:相对于简化力模型,基于致动线方法的耦合分析模型可以有效且准确模拟分析浮式风机系统的气动-水动力性能.In this study,an unsteady actuator line model（ UALM） coupled with a two-phase CFD solver is used to solve 3-D N-S equation to focus on the coupled dynamic response of an aerodynamics-hydrodynamics-mooring system for a floating offshore wind turbine named OC3-hywind Spar. The numerical analysis is divided into two parts： first,the aerodynamic loads from the upper rotor is simplified into aconstant thrust to be applied to the platform; second,the UALM model is embed into the CFD solver called naoe Foam-SJTU to obtain the fully coupled dynamic effects with wind and wave excitation. Comparisonof the results conducted by a simplified model and a fully coupled modelshows that the fully coupled model based on UALM can handle the interactive effects between the platform motion and aerodynamic loads more efficient and accurate.
