With the rapid development of the city, more and more attention has been paid to the air quality of street canyon.We numerically investigate the air flow and pollutant dispersion in the street canyon with different window opening percentage, different wind speed and roof shapes. The results show that the window opening area leads to a significant improvement of removing pollutant out of street canyon, especially for pollutants distributed on upsides of leeward and windward walls.With increasing window opening percentage, the pollutant concentration K distributed on downsides of leeward and windward walls gradually decreases. With the growth in wind speed, the pollutant concentration K also drops. The slanted roof shape may be a better choice to improve the efficiency of pollutant removal.
