摘要:本文使用开源CFD软件工具OpenFOAM，通过设置不同的建筑表面网格尺寸和不同的网格类型，计算建筑风环境的人行区风速分布情况，并按照绿建相关标准进行结果统计。通过对比分析，发现在不同的建筑表面尺寸下，贴体网格的算例中，高风速和低风速的面积占比相对较多，非贴体网格的算例中，面积占比大部分集中在中等风速。由此可以看出，贴体网格的计算结果能更好的预测高低风速的区域，因此建议使用贴体网格进行建筑室外风环境的仿真计算。
Abstract: In this paper, by using the CFD open-source tool OpenFOAM, the wind speed distribution in the pedestrian zone is studied for the building wind environment with different building surface mesh sizes and different mesh types according to the relevant green building standards. It is found that under different building surface sizes, the area ratio of high and low wind speed is higher than middle wind speed between snap and no snap mesh. The area ratio of medium wind speed is higher than the others between snap and no snap mesh. Therefore, it is recommended to use a snap mesh type to simulate the outdoor wind environment of the building.
