摘要

摘要我们通过基于自由尾流面板方法的数值模拟,研究了喘振、起伏和偏航风力涡轮机的空气动力学。我们关注的是UNAFLOW(FLOating风力涡轮机的不稳定空气动力学)案例:一台通过实验和各种数值方法建模的喘振风力涡轮机。对于具有喘振运动的推力的振幅和相位,观察到与实验数据的良好一致性。我们获得了风力涡轮机尾流的数值结果,该结果准确地再现了实验验证的喘振运动的影响。然后,我们将模拟扩展到UNAFLOW实验的频率范围之外,并得出不遵循喘振准稳态响应的结果。最后,对涡轮在偏航和升沉运动中进行了仿真,并考察了尾流运动对叶片推力的影响。我们的工作试图为UNAFLOW案例的结果库提供一种不同的方法,同时将分析扩展到以前没有模拟过的条件,并深入了解风力涡轮机运动的非线性空气动力学效应。

Nonlinear inviscid aerodynamics of a wind turbine rotor in surge, sway, and yaw motions using a free-wake panel method
Abstract. We investigate the aerodynamics of a surging, heaving, and yawing wind turbine with numerical simulations based on a free-wake panel method. We focus on the UNAFLOW (UNsteady Aerodynamics of FLOating Wind turbines) case: a surging wind turbine which was modeled experimentally and with various numerical methods. Good agreement with experimental data is observed for amplitude and phase of the thrust with surge motion. We achieve numerical results of a wind turbine wake that accurately reproduce experimentally verified effects of surging motion. We then extend our simulations beyond the frequency range of the UNAFLOW experiments and reach results that do not follow a quasi-steady response for surge. Finally, simulations are done with the turbine in yaw and heave motion, and the impact of the wake motion on the blade thrust is examined. Our work seeks to contribute a different method to the pool of results for the UNAFLOW case while extending the analysis to conditions that have not been simulated before and providing insights into nonlinear aerodynamic effects of wind turbine motion.
