| Abstract: | This paper summarizes the mechanism and study methods of pollutant distribution in urban street canyons.The air flow and pollutant distribution in Hangzhou Zhongshan Road canyons are simulated by applying CFD software.Based on the results of the experimentation,it researches the space form of street canyons and the pollutant distribution in three-dimensional space from plane section,vertical section and transect.Then,it generalizes the basic rules between street canyon form and pollutant distribution.Some planning and design methods are also presented to ameliorate ventilation and pollutant distribution. |
