A COMPUTATIONAL FLUID DYNAMICS STUDY OF STREET-LEVEL VENTILATION IN URBAN AREAS

摘要：

Introduction Economic activities and industrialization unavoidably lead to degrading street-level ventilation and elevating pollutant concentrations in urban areas.Buildings,skyscrapers and infrastructures in metropolises collectively form complicated urban morphology in which the dynamics is different from that in the atmospheric boundary layer(ABL) aloft.Under this circumstance,the conventional(meso-scale) meteorology models would not be fully applicable to diagnose the problems in details 1,2,3.Engineering computational fluid dynamics(CFD),such as OpenFOAM 4,is commonly used to tackle the problems in refined micro-scale.The protocol of using building information for OpenFOAM CFD studies in the city ventilation perspective is reported in this paper.
