摘要

本研究通过孔径为0.22 μm、孔隙率为70%的疏水纳米多孔膜，研究了微通道内的排气特性。共制作和测试了三个微通道，包括蛇形、平行和收缩-膨胀结构。质量通量(G)分别为5、7.5和10 kg/m2s，质量(x)范围为0 ~ 0.1。在不同的实验条件下，对气泡的运动进行了可视化观察。试验结果表明，气塞的接触时间、形态以及通道内流型的发展与排气量密切相关。

A visualization study of venting gas via hydrophobic nanoporous membrane

This study examines the venting gas characteristics in a microchannel through a hydrophobic nanoporous membrane with a pore size of 0.22 μm and a porosity of 70%. A total of three microchannels were made and tested, including a serpentine, a parallel and a contraction-expansion configuration. The mass flux (G) is 5, 7.5 and 10 kg/m2s with the quality (x) ranging from 0 to 0.1. Flow visualization is also performed to observe the bubbles movement under different experimental conditions. The tested results show that the amount of venting gas is strongly related to the contact time and configuration of gas slug and the development of flow pattern in the channel.
