| Abstract: | 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 ... |
