“…The inverted annular flow is characterized by a cylindrical liquid core surrounded by coaxial annulus of the gaseous film outside the heating tube wall [8]. The generation of tubular co-flowing jet flow can be concluded into two points: firstly, the generation of short liquid column depends on the collision and coalescence of slugs; secondly, the shear stress drives the gourd-shaped liquid waves upwards resulting in the squeezed liquid in the radial direction and the increased axial length of the liquid column.…”

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.

“…Huh et al (2009) observed various inverted types of flow in air-water flows. Detailed stability analyses concerning this topic are available in literature, e.g., Yan et al (2003). Micro channels have perimeters typically less than 1 cm, thus smaller than the typical Taylor wavelength obtained by the Kelvin-Helmholtz instability.…”
