By using the theory of Taylor bubbles, the dynamic profile of the deposited liquid film is calculated within the lubrication approximation ing for the finiteness of the film length, i. The latter is assumed to be pinned on a surface defect and thus immobile; the contact angle is allowed to vary.
Liquid film dynamics with immobile contact line during meniscus oscillation
The fluid flow effect on the curvature in the central meniscus part is neglected. This curvature varies in time because of the film variation and is determined as a part of the solution. The film dynamics depends on the initial contact angle, which is the maximal contact angle attained during oscillation.
The average film thickness is studied as a function of system parameters. The numerical are compared to existing experimental data and to the of the quasi-steady approximation. Finally, the problem of an oscillating meniscus is considered ing for the superheating of the capillary wall with respect to the saturation temperature, which causes evaporation.
When the superheating exceeds a quite low threshold, oscillations with a pinned contact line are impossible and the contact line recession caused by evaporation needs to be ed for. View all Google Scholar citations for this article. Alert.
