Two different types of split-recombine micromixers have been tested for a gas/liquid dispersion. Mixing performances of two micromixers have been compared in terms of a mixing efficiency. The effects of liquid flow rates, the ratio of gas/liquid flow rate, bubble sizes, and bubble size distributions have been investigated. The sequential split micromixer and the caterpillar micromixer showed a consistent mixing performance at various flow rates. The sequential split micromixer has shown the smaller and narrower bubble size distribution than that of the caterpillar micromixer at a higher flow rate of 1.8 L/h.
