充填物板上での液膜流に関する実験

（板表面構造の影響）

抄録

In separation technology, liquid film flow is used in applications such as absorption tower, for example. In general, packings are used to increase the wetted surface area because increase of wetted surface area is one requirement to improve the separation performance. Therefore, It is important to estimate critical Weber number at which the triple-phase contact line starts to advance and wet the wall. A simple theoretical model which estimates critical Weber number was proposed and the calculated results approximate well the experimental results measured in this study.
