Abstract The actuator line method is implemented into a residual-based variational multiscale (VMS) fluid modelling framework to simulate airflow around a wind turbine. In the actuator line method, the turbine blades are represented as rotating lines of body force applied to the flow field. The NREL 5MW turbine is simulated first to validate the model for a large scale reference turbine and investigate the effect of model parameters such as the width of the body force projection and the mesh resolution. The wind turbine designed by Norwegian University of Science and Technology and the NREL Phase VI wind turbine are simulated next and results are compared with the corresponding wind tunnel experiments. Velocity deficit and turbulence kinetic energy in the wake region between three and five down-stream diameters show good agreement with experimental data. We conclude with a view towards using this framework in an integrated simulation of a wind farm in complex terrain by simulating a single turbine in an area of complex terrain.

在变分多尺度框架中应用的风力涡轮机建模的执行器线方法

摘要 执行器线方法被实施到基于残差的变分多尺度 (VMS) 流体建模框架中，以模拟风力涡轮机周围的气流。在致动器线方法中，涡轮叶片被表示为施加到流场的体力的旋转线。首先模拟 NREL 5MW 涡轮机以验证大型参考涡轮机的模型，并研究模型参数的影响，例如体力投影的宽度和网格分辨率。接下来对挪威科技大学设计的风力发电机组和NREL VI 阶段风力发电机组进行仿真，并将结果与​​相应的风洞实验进行比较。三个和五个下游直径之间的尾流区域中的速度赤字和湍流动能与实验数据显示出良好的一致性。我们的结论是通过在复杂地形区域模拟单个涡轮机，在复杂地形中的风电场综合模拟中使用该框架。
