Research Abstract

Liquid infiltration characteristic on closed end tubes are experimentally investigated. By comparison to the capillary rise phenomena in a small tube, surface tension force is not enough to fill closed end tubes. Forced liquid infiltration experiments by applying the pressure reveal that the compression of inside air is the dominant factor for the tube wetting and the dissolve effect of air to liquid which have been taken into account to the theoretical model of wetting has a small impact.
