液体再夹带是先前分离的液滴脱离气液界面并悬浮在气体中的过程。重新夹带过程通常分为两个步骤。首先，高气速会在气液界面产生扰动，如波浪和波纹。其次，气体通过从高速气体到低速液体的动量传递，从其表面剪切了一些液体。这一过程与将液滴从气体中沉淀出来的预期结果相反。本文是对前两篇关于水平分离器设计的文章的补充。这里给出的方程是基于Ishii和Grolm提出的相关性。
Liquid re-entrainment is the process of previously separated liquid droplets breaking away from the gas/liquid interface and becoming suspended in the gas. The re-entrainment process generally occurs in two steps. First, high gas velocity produces disturbances in the gas/liquid interface, such as waves and ripples. Secondly, the gas shears some of the liquid from its surface through momentum transfer from the high-velocity gas to the low-velocity liquid. This process reverses the desired result of settling liquid droplets out of the gas. This article supplements two earlier articles on horizontal separator design. The equations presented here are based on correlations proposed by Ishii and Grolm.
