Abstract

This study is a basic research to enhance heat transfer between two immiscible liquids by dropping a water droplet between a wire electrode and a cylindrical electrode in silicone oil and applying an electric field. The purpose of this paper is to clarify a part of the motion behavior of the water droplet under non-uniform electric field. As a result, the water droplet apparently reciprocated between a pair of the electrodes, in case of a wire and a cylindrical electrode under the Coulomb force. The droplet stopped at a distance from the wire electrode. At that time, when a part of the water droplet extended and contacted the wire electrode, charge exchange occurred.
