N2 - We report on the underlying mechanism of spontaneous displacement of liquid plugs induced by surface tension in a small confined geometry (e.g., capillary tube). Experimental results show that the plug displacement is due to the instantaneous increase in kinetic energy that results from the surface tension between liquid plugs. Thus, the distance between plugs, which is inversely related to the surface tension energy, modulates the displacement speed and the total travel distance of the plugs. Our study provides an important basis for understanding flow phenomena of liquid plugs within small geometries.
