Homogeneous and rapid mixing in microfluidic devices have always been the premise requirement due to its integration with bioengineering and chemical experiments. In this work, a novel passive micromixer with modified asymmetric lateral wall structures is designed. The numerical simulation is carried out at the Reynolds number ranging from 0.1 to 100 for the novel microchannel and the ordinary S-shaped microchannel. The results indicate that, compared with the S-shaped micromixer, the novel structure exhibits superior mixing performance, which can be attributed to the increasing inertial effect and formation of secondary flow. The simulation results suggest that the novel micromixer developed here will achieve an efficient mixing performance.
