Abstract

Micromixers have a wide application in the biomedical engineering and chemical industry. The passive micromixer is now widely studied because it is simple and easy to fabricate. In this study single plates applied in a convergent-type flow channel are utilized to enhance the flow mixing at a lower Reynolds number. Results show that good flow mixing could be achieved in a convergent-type flow channel. The highest flow mixing efficiency, 0.974, is found at the optimal combination of Re = 80 and plate dimensions of J = 45 μm, G1 = 15 μm, and G2 = 3 μm. Furthermore, the flow mixing in the case of using plates is found to be better than the case of without them. These findings will be useful in the future design of a micromixer.
