摘　　要：本文给出了一项在南京大学 NJU 环境风洞中实施的实验模拟研究。试验模拟一座位于城市街区的排放塔的废气排放,通过流场测量,放烟显示和示踪气体扩散试验,分析气流分布与污染物浓度分布,得出对局地环境影响的一些结论。文中还以模拟扩散试验资料为实验基础,建立修正的扩散模式,探讨污染物浓度预测的可靠途径。研究结果表明,风洞流体模拟手段是有成效且实用的。An experimental modeling study executed in NJU meteorological wind tunnel was described in this paper.Atmospheric pollution affected by the wast gas from a tower located at downtown ofa big city has been simulated.By means of measuring the flow field and flow visulization and dis-persion test by releasing the tracer,some conclusions concerning the impact of atmospheric pollu-tion on the local environment have been obtained.Based on the experimental data of the disper-sion test,a modificative dispersion model has been developed in order to explore the actual ap-proach to predict the air pollutant concentration and its distributions.The results show that fluidodeling in wind tunnel is an effective and practical method.
