Study on stretching liquid bridges with symmetric and asymmetric surface wettability

Abstract

The rupture process of stretching liquid bridges is determined by competition between contact line slip velocity and liquid bridge thinning velocity. Poorer surface wettability and larger stretching velocity help increase slip velocity and enable the liquid bridge to slip off surfaces. In addition, the shift moment of minimal radius of stretching liquid bridges is related to surface wettability, regardless of plate stretching velocity. Finally, satellite drop formation is related to the sequential order of appearance of the liquid bridge slipping off the plate and the breakup of the filament.
