Fates of a Nonwetting Slug in Tapered Microcapillaries under Gravity and Zero Gravity Conditions : Dynamics, Asymptotic Equilibrium Analysis, and Computational Fluid Dynamics Verifications
It has been determined experimentally and numerically that a nonwetting slug in a tapered capillary tube, under the sole action of capillary force, self-propels itself toward the wider end of the tube until an equilibrium state is reached. The aim of this work is to highlight the state of the slug a...
