Abstract: Vehicle pollutants dispersion in urban street canyon was evaluated by numerical simulation.Mathematical model of vehicle pollutants dispersion was introduced,and pollutants concentration distribution in street canyon was simulated.The characteristics of vehicle pollutants dispersion in street canyon were obtained,and influence of street configuration was discussed.Research results will be helpful for inspecting,evaluating,and preventing atmosphere pollution in urban street.

Key words: urban street canyon, numerical simulation, fluid flow, pollutants dispersion
