| 摘 要： | 空气动力阴影区是在风的作用下建筑物背风侧和顶部的旋涡区。当建筑物附近有污染源存在时，污染物的浓度分布与污染源和空气动力阴影区之间的相对位置有着密切关系。以一高层建筑为例，采用数值模拟的方法，探讨和分析污染源在空气动力阴影区内外几个不同相对位置时，建筑物周围污染物分布的不同。

| Abstract: | The aerodynamic shadow zone means an area of vortex caused by wing field, which lies in the leeward side and the top of build-
ing. When there is contamination resource around a building, there is dose relationship between the distribution of concentration of contami-
nation and the relative place between the contamination resource and the aerodynamic shadow zone. Regarding a high building an an example,
the method of numerical simulation is adopted to discuss and analyze the different distribution of concentration around the building which re-
suits from the different relative places of contamination resource in the aerodynamic shadow zone. |
