In this study, the authors used the split-and-recombine (SAR) structure as an acceleration method of mixing and chemical reaction with small fluid quantities and a short time in a micro channel. By using this structure, the number of layers of two reacting fluids can increase. Then, the contact areas increase, the thicknesses of layers decrease, and the mixing and chemical reaction are accelerated. In a three-successive-SAR structure, we performed the experimental which visualized the flow of 10mm/s (Re=4.58) by chemical luminescence. As a result, the number of layers of two reacting fluids increased and the reaction was accelerated. The reaction efficiency of the three-successive-SAR structure was 66.7% which was accelerated about 5.0 times compared with a simple straight channel.
