Abstract

In this paper, we evaluate the influence of various micromixer designs on the mixing efficiency of passive micromixers. We analyze the designs of various passive micromixers to identify the most efficient micromixer. Among them, the toroidal micromixer and 3D zig-zag micromixer demonstrated the highest mixing efficiency. We investigated the key factors influencing mixing in the toroidal and 3D zig-zag micromixer, identifying and confirming optimal designs. Ultimately, when comparing the mixing efficiency of the two micromixers, the 3D zig-zag micromixer achieved full mixing in a very short time of 0.8 ms. Through this research, it is anticipated that a benchmark will be provided for micromixer design in microfluidic devices when manufacturing micromixers of various forms.
