From: A millisecond passive micromixer with low flow rate, low sample consumption and easy fabrication

The structure details of the complete mixing compartment studied in this paper in top (a) and side views (b). The mixer is composed of three zones: SHB pre-mixer, SHB center channel and ring-shape units. The mixer region is built out of two separate layers: the top one contains the SHB ridges and the bottom one the double-T pre-mixer channel. Several ring-shaped units are also combined with the main channel on the bottom layer during fabrication. (c) The four different arrangements of the SHB including the one shown in (a,b), for a total of four SHB designs for the double T structure, marked A, B, C and D. The 3D sketches shown on this figure were made with the SOLIDWORKS 2020 software (http://www.solidworks.com).
