通过分析风力机运行时竖直方向上风速及湍动能的变化情况,研究多台风力机运行对近地边界层的潜在影响。采用Gambit软件建立多台风力机及风场模型,并利用Fluent软件对4台风力机顺列和错列2种布置方式下的流动进行数值模拟。结果表明:由于风力机的转动,对近地边界层中的速度和湍动能分布都带来一定的影响,同时,边界层高度也随速度沿竖直方向分布的不均匀性而增高;不同高度处风速和湍动能的变化规律是不同的;在距离风轮上部3倍直径高度处,速度沿流向开始有小幅度的降低,且错列布置速度衰减幅度要高于顺列布置时;湍动能沿流向逐渐降低,在叶轮位置上空处有着阶跃型变化,整体上错列布置湍动能要高于顺列布置同一位置处。“,”By analyzing the variation of the wind speed and turbulent kinetic energy in the vertical direction of the wind turbine, the potential influence of the operation of multiple wind turbines on the surface boundary layer was studied. Gambit software was used to establish multiple wind turbine and wind field model, and the Fluent software was used to simulate the flow of four sets of wind turbine in parallel and stagger arrangement. Results show that the velocity and turbulent kinetic energy distribution in the surface boundary layer are affected by the rotation of the wind turbine. The boundary layer height is also increased with the inhomogeneous velocity distribution along the vertical direction. The variation regularity of wind speed and turbulent kinetic energy is different in different altitude. In the three times diameter height over the wind turbine, the speed of the flow is reduced along the streamwise direction, and the velocity decay in stagger arrangement is much higher than that of in parallel arrangement. The turbulent kinetic energy decreases along the flow direction, and it has a step change over the impeller position. On the whole, the turbulent kinetic energy in staggered arrangement is higher than that in the same position of parallel arrangement.
