在本文中，使用两个无量纲参数将三种不同除雾器作用于三种不同流体系统（Exxsol D60/氮气、合成天然气和真实天然气）在压力高达 114 bara 的情况下的分离效率结果汇总在一起：(1) 再夹带参数和 (2) 韦伯数。可以实现这一点的事实表明，可以通过采用针对重力膜中的液膜导出的再夹带概念来对受再夹带限制的除雾旋风器进行建模。
In this paper, separation efficiency results for three different demisters acting on three different fluid systems, Exxsol D60/nitrogen, a synthetic natural gas, and a real natural gas at a range of pressures up to 114 bara, are brought together using two dimensionless parameters: (1) a re-entrainment parameter and (2) the Weber number. The fact that this can be achieved shows that demisting cyclones limited by re-entrainment can be modeled by adapting re-entrainment concepts derived for liquid films in a gravity film.
