摘要
基于计算流体动力学(CFD)的数值模拟方法,采用三种湍流封闭模型研究了某体育馆工程的屋面平均风压系数的分布情况,并与风洞试验数据进行了比较,分析了建筑屋顶的风速矢量图,进而解释建筑屋顶来流绕流规律。
Based on the numerical simulation method of Computational Fluid Dynamics （CFD）, the distribution of the roofing mean wind pressure coeffieient for a gymnasium building is studied using three kinds of turbulence closed models and is compared with the wind tunnel test data. Furthermore, this paper analyzes the wind speed veetogram of the building roof and interprets rules of coming-flow and circulation current of the building roof.
