  • Control of behavior of O/W emulsions using electric fields

抄録

<p>In this paper control of oil droplet in O/W (Oil-in-Water) emulsion (EM) stream is attempted. These oil droplets are positively and negatively charged by the cationic and anionic surfactants, respectively. The behavior is controlled by applying an electric field to the EM charged with a surfactant. The experiment is carried out in a flow path that branches in two directions. EM flow in this flow path. Iron plates are set on the side of flow path. Iron plates are connected to constant voltage power supply. EM is applied an electric field. An electric field is applied from the side walls of flow path. Oil droplets are guided to one branch. An electric field strength is controlled by the applied voltage. The applied voltage is increased. Oil droplets move to the electrode. Oil droplets are passed through one branch. Oil droplets are changed the direction of branches by type of surfactants.</p>
