摘　　要：在工程建设之前,对风环境进行模拟能够很好的避免空间规划和风场分布方面的不足,大大降低了成本和不安全的因素。运用了fluent软件对某一区域建筑群周围风环境进行了数值模拟。模型计算区域的网格划分采用具有良好适应性的非结构化四面体网格,并采用了扩展k-ε湍流模型。给出不同的建筑布局图,并通过fluent软件模拟出不同布局下计算区域的风速图。最后从自然通风和行人安全性、舒适性的角度出发对不同建筑布局下的风环境模拟结果进行了讨论和分析。Simulating the wind environment before constructing buildings have many advantages.Firstly,it can avoid the lack of spatial planning and wind field distribution.Secondly,it will greatly reduces the cost and insecurity.Fluent software was used to simulate the wind environment around group buildings.And unstructured tetrahedral grids was used to mesh the model,because this kind of method has a good adaptability,extended k-ε turbulence model was used in this research.Different building layout was built and regional wind speed maps were calculated by fluent software.At last,this paper analyzed the simulation results from the perspective of natural ventilation and pedestrian safety.
