Abstract

In this paper, we used CFD-ACE software to investigate fluid mixing of the rhombic micromixer with flat angles. According to the results of the numerical simulations, this rhombic microchannel with flat angles showed high mixing efficiency compared to cross-shape straight microchannel. Over 95% mixing efficiency had been achieved at Re > 180 due to enhancement of vortices. In processing, CO₂ laser machining is used to fabricate the master mold easily instead of conventional photolithography process. From results of the mixing experiment, high Reynolds number resulted in better fluid mixing because of stronger Dean vortices and recirculation effect.
