Advanced Numerical Framework for Wind Turbines in Atmospheric Boundary Layer Flow

现代风力涡轮机在非常复杂的湍流大气边界层（ABL）中运行，具有宽范围的含能长度尺度和不同的大气稳定性区域。当风力涡轮机与ABL相互作用时，叶片在旋转周期期间经历负载和扭矩的显著变化。这直接影响风力涡轮机的气动性能、功率生产和叶片结构响应。当风力涡轮机排列成阵列时，这个问题就放大了。在这种配置中，任何顺风涡轮机都在逆风涡轮机的尾流中操作，这增加了功率生产的损失并且由于尾流相互作用而降低了疲劳寿命。

Modern wind turbines operate in the very complex turbulent Atmospheric Boundary Layer (ABL) with a wide range of energy-containing length scales and with different atmospheric stability regimes. When wind turbines interact with the ABL the blades experience significant variations of the loading and torque during the rotation cycle. This directly affects the wind turbine aerodynamic performance, power production and blade structural response. The problem amplifies when wind turbines are arranged in arrays. In this configuration any downwind turbines operate in a wake of upwind turbines, which increase losses of power production and reduce the fatigue life due to wake interaction.
