摘要
本文对位于上海市浦东金融中心区的越江隧道排风井的形式与污染物扩散特征进行了CFD模拟预测。首先开发了基于点群格式的GIS数据及GIS数据与CFD的接口,此接口可大大提高对包含大量建筑物的城区规模的CFD分析的建模效率。而后应用基于GIS数据生成的CFD模型,对隧道低风井方式和高风塔方式进行了污染物扩散影响对比分析,指出该地区采用低风井排放方式能够满足大气环境评价标准。
In this paper,the types of cross-river tunnel exhaust shafts and the characteristics of contaminant diffusion in urban area in Shanghai were simulated by CFD software. Firstly, group point format GIS data and its CFD interface were developed, with this interface, the modeling efficiency could be highly improved. Secondly, based on the GIS generated CFD model, the comparative study on contaminant diffusion with high and low exhaust shafts were presented. The CFD results indicated that the low exhaust shaft could satisfy the criteria of atmospheric environment.
