中文摘要：
一个新计算集体转移模型为由解决波动的集体流动让狂暴的集体转移方程的闭合以便获得集中侧面和蒸馏列的分离效率模仿蒸馏过程被建议。建议模型的羽毛是放弃把狂暴的集体转移扩散性(分散系数) 介绍给狂暴的集体转移方程的常规方法。为了验证建议模型，的有效性，商业规模包装了列，筛托盘列被模仿并且与出版试验性的数据相比。模仿的结果令人满意地在集中分发和分离效率被证实。
英文摘要：
A new computational mass transfer model is proposed for simulating the distillation process by solving the fluctuating mass flux u^＇ic^＇ for the closure of turbulent mass transfer equation in order to obtain the concentration profile and the separation efficiency of distillation column. The feather of the proposed model is to abandon the conventional way of introducing the turbulent mass transfer diffusivity （dispersion coefficient） to the turbulent mass transfer equation. To verify the validity of the proposed model, a commercial scale packed column and a sieve tray column were simulated and compared with published experimental data. The simulated results were satisfactorily confirmed in both concentration distribution and senaration efficiency.
