浮式平台上的海上风力涡轮机将经历比可比的底部固定式风力涡轮机更大的运动，大多数行业标准设计规范已经开发和验证。本文研究了周期性喘振运动对风力机涡轮机转子的综合载荷和诱导速度的影响。具体而言，性能的叶片元素动量理论与准定常尾迹，以及两个广泛使用的工程动态入流模型进行了评估。一个移动的致动器盘模型被用作参考，因为与尾流相关的动力学将固有地包括在相关的流体动力学问题的解决方案中。通过综合转子载荷、诱导速度和气动阻尼的分析，得出结论：典型的喘振运动足够慢，不会显著影响工程模型预测的尾流动力学。版权所有© 2012约翰威利父子有限公司.
Offshore wind turbines on floating platforms will experience larger motions than comparable bottom fixed wind turbines—for which the majority of industry standard design codes have been developed and validated. In this paper, the effect of a periodic surge motion on the integrated loads and induced velocity on a wind turbine rotor is investigated. Specifically, the performance of blade element momentum theory with a quasisteady wake as well as two widely used engineering dynamic inflow models is evaluated. A moving actuator disc model is used as reference, since the dynamics associated with the wake will be inherently included in the solution of the associated fluid dynamic problem. Through analysis of integrated rotor loads, induced velocities and aerodynamic damping, it is concluded that typical surge motions are sufficiently slow to not affect the wake dynamics predicted by engineering models significantly.
