| 摘 要： | 风电场中风机之间存在十分复杂尾流相互干扰现象,尾流相互干扰效应对风机的功率输出、叶片载荷等产生十分显著的影响。采用致动线模型以及计算流体力学方法,研究两风机之间的复杂尾流干扰效应。在保持两风机纵向间距一样的情况下,考虑两风机在不同横向间距下,数值模拟两风机的部分尾流相互干扰现象,分析两风机的气动功率输出特性、尾流速度变化特性、风轮平面附近轴向诱导因子分布特性,尾涡结构以及尾流干扰效应。数值模拟结果表明:在上下游风机在沿着流向方向距离保持不变的情况下,随着横向间距的变化,上下游风机的尾流存在十分复杂的尾流相互干扰效应,对下游风机的气动功率输出以及两风机风电场的整体流场产生了显著的影响。

| Abstract: | There is complex and significant phenomenon of wake interaction which has great influence on the aerodynamic power output, blade loads and flow speed for turbines in the wind farm. In this study, the actuator line model(ALM) combined with CFD technique is applied to study the complex phenomenon of wake interaction between two offset-line model wind turbines. In the case of maintaining the longitudinal spacing of the two wind turbines, numerical simulations are conducted to study the characteristics of aerodynamic power output and wake speed variation and the wake interaction under different cross spacings. The results of numerical simulation show that with the change in lateral spacing, there is complex and significant wake interaction of upstream and downstream wind turbines, which has prominent impact on the power output, the mean wake velocity and the vortex structure. |
