Abstract One-dimensional two-fluid mass, momentum, and energy conservation equations for gas and liquid droplet and the particle removal rate are formulated to estimate aerosol particle removal rates of venturi scrubbers used in filtered containment venting systems. Compared with existing one-dimensional models, present method enables describing actual two-phase interactions by calculating the local gas and droplet velocities hence local droplet diameters as well as the other physical properties. The results show that the particles are mostly removed at the entrance region of the throat where droplets are introduced and thus the two-phase velocity difference is the largest. This coincides well with previous experimental studies. The present model predicts the existing experimental data considered here better than the previous one- or two-dimensional models. Especially, in the conditions of low liquid-to-gas flow ratio, the predictions of the present model are very close to the experimental data.

使用一维二维流体方程估算过滤式安全壳通风中文丘里洗涤器的气溶胶颗粒去除率的方法

摘要 制定了气体和液滴的一维二维流体质量、动量和能量守恒方程以及颗粒去除率，以估计用于过滤式安全壳通风系统的文丘里洗涤器的气溶胶颗粒去除率。与现有的一维模型相比，本方法能够通过计算局部气体和液滴速度、局部液滴直径以及其他物理特性来描述实际的两相相互作用。结果表明，颗粒大部分在引入液滴的喉部入口区域被去除，因此两相速度差最大。这与之前的实验研究非常吻合。本模型比以前的一维或二维模型更好地预测了这里考虑的现有实验数据。特别是在低液气流量比的条件下，本模型的预测与实验数据非常接近。
