Recently, study of the micro chemical process that uses slug flow has been active. Slug flow is the flow which appears as striped patterns in micro channels. Slug flow increases reaction speed and mixing efficiency of chemical reactions. In this study, The good of this research generation / separation operations of the slug flows, which is not depend on gravity, flow quantity and the viscosity of the fluid. For this purpose we have developed dynamic slug flow generation / separation technique using electromagnetic valves. We devise a new electromagnetic valve and made a design, manufacture and an experiment. As a result of experiment, the width of the pitch of water and oil can be miniaturized to 0.56 mm and 0.29mm respectively. On slug flow separation, we applied to highly viscous liquid separation.
