For ice storage, one of authors has studied new ice slurry formed by cooling water-oil mixture with stirring. When the mixture is stirred in a vessel, the oil is charged by static electricity due to friction. If the vessel can attract charged oil, prevention of ice adhesion to cooling wall may be realized. There for, in this paper, in order to observe behavior of charged oil-water droplet or mixture in a electric field by a high speed camera or video camera, two types of experiments were carried out. One was that oil-water droplet charged by static electricity was made to fall plumb down between two electrodes with electric field or without electric field, varying the water content of droplet. The other was that a constant voltage was applied on the vessel filled with oil-water mixture with stirring. From the observations, it was confirmed that attracting force between the charged wall(electrode) and charged oil acted.
