Miniaturized flow control devices have recently gained considerable attention in chemical process engineering and biotechnology. Miniaturized flow control devices include micromixers, microvalves, and micropumps in the fields of miniaturized chemical analysis systems such as micro total analysis systems (μTAS), and miniaturized production systems. Mixing of the fluid flowing through microchannels is important in a variety of applications. At low Re, in simple channels, pressure flows are laminar and uniaxial, so the mixing of material between streams in the flow is purely diffusive. Therefore, a micromixer with thermocapillary effect is proposed. The flow structure in this micromixer is three-dimensional spiral flow. In this study, the mixed effect by this method was confirmed.
