摘要
利用CAD软件建立三维物理模型,采用Fluent软件RNG k-ε模型,分析了SO_2污染物排放扩散的分布规律.结果表明:风速是影响大气污染物浓度分布的最主要因素,污染物的浓度随着风速的增大而减小,这对了解工业城市气体污染物传输扩散过程有一定指导意义.
CAD software was used to build a 3-D physical model and the RNG k-ε model was used to analyze the distribution of S02 e- missions diffusion in the Industry Park of Baotou Iron and Steel （Group） Co.. The results show that wind speed is the main factor affect- ing the distribution of the pollutant diffusion concentration in the atmosphere . The concentration of the air pollutants decreases with the increase of the wind speed, which may provides some theoretical reference for understanding the transfer process of gaseous pollutant diffusion in the industrial cities.
