Shape and size of the entrained liquid mass by a Taylor bubble rising through a liquid-liquid interface

Abstract

Long gas bubbles in circular tubes, called Taylor bubbles, occur frequently in industrial applications. If the tube contains two immiscible liquids, one on top of the other, a rising Taylor bubble after passing though the interface entrains some heavier liquid that was below the interface into the liquid that is above the interface. This article reports different shapes and sizes of the entrained mass as it rises sticking to the tail of rising Taylor bubbles of different volumes.
