摘要
The numerical simulation of wind tunnel experiment was carried out by using the inverse problem method, and the numerical simulation data was compared with the wind tunnel experimental results. The paper analyzed the results at different observation points in the street canyon with different Schmidt numbers. The results show that, when the Schmidt number ranges from 0.7 to 0.8, the numerical simulation results of the convective gas in the street model and the experimental results in wind tunnel are close greatly, indicating that the Schmidt number of air pollutants disperse in city streets is between 0.7 to 0.8.
