摘要
借助反问题方法对风洞实验工况选取不同施密特数进行数值模拟试验，分析比较了不同施密特数时街道峡谷内各个观测点的数值模拟数据和风洞实验数据．研究结果表明，城市街道内大气污染物扩散的施密特数为0．7～0．8．
For determining the Schmidt number of gaseous pollutants diffusion in urban streets, the inversion theorem was introduced. The systematic numerical simulation of the wind tunnel experiments under different Schmidt numbers for examing gaseous pollutants dispersion in urban streets was carried out and the results were processed by analysing and comparing with the test data. It is found that the results of numerical simulation agree well with the wind tunnel experimental data in the specially designed tests when Schmidt numbers range is from 0.7 to 0.8.
