Abstract

The behavior of liquid that rises to the top of a short tube depends on the Weber number We defined as the ratio of the kinetic energy of the liquid and a reference surface energy. In optimal experiments with diethyl ether, the meniscus of the rising liquid inverts and spreads onto the external surface of the tube when We greater than or similar to 1. If We less than or similar to 1, the meniscus remains pinned at the top of the tube. For inertial capillary rise dynamics the maximum kinetic energy is achieved when the height of the liquid column is 3/4 of the equilibrium rise height and diverges with decreasing gravitational acceleration.
