Bubble Cutting by Cylinder – Elimination of Wettability Effects by a Separating Liquid Film
Abstract: Experiments and simulations are presented for the interaction of single bubbles rising in a viscous liquid against a horizontal cylinder (Ø = 4 mm) of varying wettability. The slide‐off of small and the cutting of larger bubbles into two daughter bubbles observed in the experiment are reproduced by phase‐field simulations. It is shown that in the entire process bubble and cylinder are separated by a liquid film, which eliminates any influence of cylinder wettability. Before the mother bubble splits, a thinning gas thread develops below the cylinder. The rupture of this gas thread can lead to a different number of satellite bubbles depending on the conditions.
