| 摘 要： | 针对建筑物的风环境问题，采用计算流体动力学CFD软件对两幢建筑物进行了数值模拟，得出了建筑物的风场分布，以及风载的分布规律，结果表明，气流在来流方向第一幢建筑物的顶部、两侧的前沿产生分离，建筑物之间产生强烈的漩涡，顶部的局部负压最大。

| Abstract: | The paper presents numerical calculations of turbulent wind flow conditions around two three - dimensional parallel buildings with the software of computational fluid dynamics. The numerical simulation are carried out with the standard model. It obtains the rules of distilbution of wind flow aroud the buildings and pressure on the buildings. The result shows that the flow separates over the top and two sides of the first building along the direction of flow ;there is a strong eddy at the street canyon- between the two buildings, and the maximal part negative pressure lies in the top of the first building. |
