| 摘 要： | 运用k-ε双方程湍流模型数值模拟了几种不同形状的建筑物和一组建筑物群周围气流绕流的三维流场．结果表明，当来流的风速相同时，不同形状的建筑物的气流绕流流场是不同的，建筑物的几何结构是影响其周围流场分布的主要因素之一；建筑物群周围的绕流过程比单个建筑物更加复杂，除了具有单个建筑物绕流过程中所产生的流动分离和回流等复杂特征外，还存在建筑物之间的互相影响。

| Abstract: | k-e turbulence model is used as turbulence model for modeling airflow about several shapes of buildings. The computed results agree well with the wind tunnel experimental data, and it is demonstrated that k-e turbulence model is suitable for the simulation of airflow around buildings and subsequently of airflow around a set of buildings. It is demonstrated that the airflow near buildings is very complicated, and has an influence on the air environmental quality near buildings. |
