【摘要】 基于叶素动量理论模型、动态叶素动量理论模型和升力线自由尾迹模型对比研究了浮式风力机纵荡过程中由于风轮尾迹的诱导作用以及翼型的非定常气动特性所导致的延迟效应，讨论了不同模型间预测结果的差异。结果表明，对于尾迹的诱导作用所带来的延迟，动态叶素动量理论模型预测的延迟角度较自由尾迹模型偏小；而对于翼型非定常气动特性所带来的延迟，在耦合动态失速模型后，叶素动量理论模型和动态叶素动量理论模型预测的延迟角度较自由尾迹模型则偏大。尽管不同模型所预测出的延迟角度值的大小存在差异，但所给出的延迟沿叶片展向的变化规律以及纵荡参数对延迟变化的影响规律相一致。更多还原

【Abstract】 The hysteresis effect of the floating wind turbine caused by the wake induction effect and the airfoil unsteady aerodynamics under the surge condition is comparatively investigated based on the blade element momentum model, dynamic blade element momentum model and free vortex wake model, and the differences between the results predicted by different models are discussed. The results show that, for the hysteresis caused by the wake induction effect, the phase lag angle predicted by dynamic blade element momentum model is smaller than that of free vortex wake model, while for the hysteresis caused by airfoil unsteady aerodynamics, the phase lag angle predicted by blade element momentum model and dynamic blade element momentum model are larger than that predicted by free vortex wake model, after coupling with the airfoil dynamic stall model. Although there are differences in phase lag values predicted by different models, the variation trends of the hysteresis along the blade and the influence patterns of the surge parameters on the hysteresis given by different models are consistent.更多还原
