WebMay 13, 2024 · Here, we study the pinch-off of a bubble in confinement in the partial wetting regime. We show that the moving contact line singularity (30, 31) dominates the viscous dissipation at early times, leading to an axially dominated flow and the emergence of an early-time self-similar regime, which then crosses over to a late-time regime, where the … WebSep 20, 2016 · In a pneumatic drop generator, jet pinch-off is an important phenomenon for detaching droplets from the liquid column. An experimental investigation on final stages of dripping droplets pinch-off was performed in Ref. [16] for water and ethanol.
