Abstract: Rapid progresses in technology of the biochip or electrochemical engineering require high-performance micromixer. Research on the flow in the microchannel is the foundation of the design for passive micromixer. In this paper, a micromixer embedded with barriers was studied numerically. It is found that the barriers periodically embedded in the microchannel are beneficial to the chaotic mixing in that the barriers can form a group of linked twist maps that possess the Bernoulli property and the chaotic advection in these regions. The mixing efficiency in the diffusion channel with barriers is much higher than that without the barriers.
