G0601-4-5 Bridging Phenomena Caused by Instability of Liquid-liquid Interface under Electric Field

Abstract

On the water/silicone oil interface that becomes unstable by applying electric field, bridging phenomena caused by water column in the oil is studied experimentally. The phenomena are photographed by use of a high speed video camera, and observed in detail. As a result, it is shown that the water droplets dispersed in the oil plays an important role for the bridge formation and hold-up of the water droplets in oil is caused by the difference between rise and fall velocities of the droplets.
