摘要
采用数值模拟技术对城市街道峡谷机动车污染物的扩散规律进行了研究。介绍了城市街道峡谷机动车污染物扩散的数学模型 ,对街道峡谷内部气流运动及污染物浓度分布进行了模拟计算 ,获得了城市街道峡谷机动车污染物的扩散规律 ,并分析了街道形状对污染物扩散的影响。研究结果可为城市街道大气污染监测、评价及防治提供科学依据。
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.
