A new sliding micro valve generating/separating slug flow in micro chemical process

Recently, the study of the micro chemical process that uses slug flow has been activated. Slug flow which is a flow of two liquids to appear as striped patterns in a channel increases reaction speed and mixing efficiency in the fields of chemical technology. Conventionally, passive slug flow generation / separation technique has been used for those purposes. But due to the specific gravity of the liquid, the flow quantity and the viscosity of the fluid, passive slug flow process results in low control accuracy of the slug length.
