Pollutant Dispersion in Open Country Street Canyon and Urban Roughness Street Canyon

YOU Xue-yi,LI Li (School of Environmental Science and Engineering,Tianjin University,Tianjin 300072,China)  
As a benchmark problem,the pollutant dispersion in a street canyon is much attended and hardly investigated.Some key problems,such as the distinction of open country street canyon and the urban roughness street canyon,the determination of computation domain and the inlet boundary condition,are usually overlooked or even mishandled when the CFD is applied in the simulation of pollutant dispersion.The methods to overcome these shortcomings are presented in this paper.The difference of pollutant dispersion in open country street canyon and urban roughness street canyon is discussed in detail.Numerical results confirm the experimental finding of Meroney et al.(1996) that the pollutant in urban roughness street canyon is harder dispersing out of street canyon than that in open country street canyon for the same condition.Our numerical results are in good agreement with the experiment of Meroney et al.
