摘　　要：采用CFD软件包FINE/TURBO和带有壁面函数的k-ε湍流模型进行复杂地形地貌风电场流场的数值模拟研究。首先以简化的二维山地模型,探索计算域的高度、长度对目标山地流场的影响,然后变化不同二维模型入口的水平过渡及连接位置,分析并给出地形边界处理的合理建议,最后针对排布简单的三维模型、风场实际地形进行讨论。CFD software package FINETM/TURBO and the k-turbulence model with wall function were numerical simulation of flow field for complex terrain wind farm. Firstly, the effect of height and length of domain on flow field in objective mountain was explored by simplified two-dimensional mountain model, horizontal transition and connecting position in the entry of two-dimensional mountain model were changed give reasonable proposal for boundary treatment of landform. Finally, actual landform of wind farm was di on three-dimensional model with simplified arrangement. used to study computational then different to analyze and scussed based
