采用NREL Phase VI风力涡轮机进行验证研究。空气动力学模拟使用有限元ALE‐VMS公式进行，并增加了弱强制本质边界条件。在所有情况下，转子被假定为刚性的，并且其旋转是规定的。仅转子模拟进行了广泛的风力条件和计算结果相比，有利的实验结果在所有情况下。采用滑动界面法对完整的风力涡轮机配置进行仿真。全风力涡轮机模拟捕捉到了叶片-塔架相互作用效应，这些模拟的结果也与实验数据吻合良好。版权所有© 2012 John Wiley & Sons，Ltd.
A validation study using the NREL Phase VI wind turbine is presented. The aerodynamics simulations are performed using the finite element ALE‐VMS formulation augmented with weakly enforced essential boundary conditions. In all cases the rotor is assumed to be rigid and its rotation is prescribed. The rotor-only simulations are performed for a wide range of wind conditions and the computational results compare favorably with the experimental findings in all cases. The sliding-interface method is adopted for the simulation of the full wind turbine configuration. The full-wind-turbine simulations capture the blade‐tower interaction eect, and the results of these simulations are also in good agreement with the experimental data.
