Abstract
The pollutant dispersion in a street canyon has been described inthis study by using an two-dimensional lattice Boltzmann method coupled to the Smagorinsky subogrid scale model. The pollutant source is divided ground-level source(GLS) and elevated source (ES). The obstacles were made a flat plate. The height of obstacle and distance of them were divided flow patterns as a isolated roughness flow, wake interference flow, skimming flow. The influence of the ratio between the height of the upstream and downstream canyon obstacles, as well as the gap distance between them was analyzed considering the situation of `open country`and `urban roughness`. The code for this reserch used large eddy simulation (LES) model by using lattice Boltzmann method(LBM).
