Abstract:

By using of Fluent CFD software, a 32d intersection model of streets is set. The wind velocitydistribution and CO concentration distribution near the intersection are simulated under 2 wind direction conditions.The result of the modeling shows that the layout of the structures and the wind direction can jointly affect thedistribution of the wind velocity and the CO concentration. The study of this paper also shows that the modelingresult of Fluent is reasonable and the application prospect of Fluent on atmospheric environment issues in urbanstreets is good.
