Abstract

Gas-liquid suction flow is common in daily life and industrial process, which normally brings problems including noises and vibrations. In this paper, we designed an experimental apparatus to investigate the whole process for liquid film suction through a tube, from liquid inundating the tube nozzle to complete detachment. Bubbly flow, slug flow, and tubular co-flowing jet flow were observed and the mechanism of flow transition was discussed. The generation of bubble/slug, the change of its length, the interaction between each other, and the whole life of small liquid column were studied in detail. We hope this study could provide a clear understanding of vibrations in the process of non-contact liquid suction and guide the design and optimization of related industrial applications.
