Abstract

The staggered herringbone chaotic micromixer has been designed based on the use of modular method and orthogonal experiment. With the modular method, the geometry of the micromixer was divided into straight channels and mixing units alternately. The mixing units were designed with orthogonal experiment. The aspect ratio of the herringbone to the microchannel (r1), the ratio of the width of herringbone to the spacing of between adjacent two herringbones (r2) and the width of the herringbone (r3) were investigated. The optimal outputs were r1 = 1:3, r2 = 1:1, and r3 = 50 µm. The micromixer was fabricated with two steps lithography method based on the presented optimal parameters, and the material of the micromixer was polydimethylsiloxane (PDMS). The optimized design method is proven to be an effective way for rapid design of the staggered herringbone chaotic micromixer.

Keywords: micromixer; design of experiments; optimal design; lithography
