城市街道机动车污染扩散模型研究动态

Study Trends on Urban Motor Vehicle Pollution Dispersion Models

城市道路机动车排放污染扩散的研究主要有2个方面:城市尺度的街道交通大气污染扩散研究和微尺度的街道峡谷大气污染扩散研究,重点介绍国外城市街道峡谷的机动车污染扩散的3种主要研究方向:实地测量法、物理风洞实验和数值模拟法的现状与进展。

There are two directions in research field of urban vehicle exhaust dispersion, namely, street pollution dispersion in city-scale and street canyon dispersion in micro-scale. On this paper, advances in urban street canyon pollution dispersion were presented, the research background and the results of main methods were introduced.
