摘要
对城市街道峡谷内大气污染的扩散模式进行了探讨,指出了应用模式一般是针对特殊的街道峡谷问题而设计的,属于半经验模式;CFD模式可以对复杂的街道峡谷内扩散问题进行微观的研究,是今后的发展趋势;物理模拟则可以对大气扩散问题进行详细研究。
This paper discusses air pollution diffusion models in urban street canyons. The models include semi - empirical model which designs for special street canyons, CFD model which makes micro - study on air pollution diffusion of complex street canyons and which is the development direction, and physics simulation which can in detail study air diffusion and which is the necessary method for testing the models.
