摘要:

利用CFD软件Fluent建立了一个三维街道十字路口模型,模拟了 2种风向条件下街区风速分布和CO质量浓度分布的情况.结果表明,十字路口的建筑物布局与风向共同作用,会对街区的风速和CO质量浓度分布产生很大影响.模拟结果表明,CFD对所建模型模拟结果合理,用于街区大气环境问题研究有着良好前景.

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.

Key words: CFD, Fluent, urban streets, atmospheric environment
