摘要
应用ｋ－ε湍流模型，对平原地区高架烟囱排烟的大气扩散现象做了数值计算，绘出了流场的速度矢量图及浓度等值线图。数值计算结果与风洞实验数据以及经验模式计算数据的定性比较表明，本文所用的数值计算方法是可行的。
Using k-ε turbulence model,this paper presents the numerical simulation process and result of flue gas and air diffusion from the high chimneys on plain area. The result includes velocity vector distribution chart and flue gas concentration isogram. By comparing quantitively the result of numerical simulation,wind tunnel testing and calculation with empirical formula,the feasibility and the reasonableness of the simulation process and result are verified.
