我们评估的平均Navier-Stokes方程可作为商业计算流体动力学代码的中性大气边界层的模拟，并试图定义一个适当的数值模拟程序。四个湍流模型，包括两个方程和雷诺应力模型，进行了评估，以及两个近壁模型。还进行了网格和地图数字化敏感性测试。模拟进行了比较，从苏格兰Askervein山的实验现场数据。结果表明，与实验结果相比，使用ANSYS CFX 12.1在适当的网格和拓扑图上使用雷诺应力湍流模型进行的模拟提供了最佳的风速预测。
We evaluate the Reynolds-averaged Navier–Stokes equations available as commercial computational fluid dynamics code for the simulation of a neutral atmospheric boundary layer and attempt to define a proper numerical simulation procedure. Four turbulence models, including two-equation and Reynolds stress models, were evaluated together with two near-wall models. Mesh and map digitization sensitivity tests were also performed. The simulations were compared to experimental field data from the Askervein Hill in Scotland. The results show that the simulations performed with ANSYS CFX 12.1 on a proper mesh and topological map with a Reynolds stress turbulence model provided the best wind-speed predictions when compared to the experimental results.
