2 Active and Passive Micromixers
Fig. 2.18 Modified Tesla micromixer [54]—schematic illustration of the principle
Owing to the development of microfabrication techniques, 3D micromixer designs
become popular. 3D micromixers have complicated the geometries, but showed
generally high mixing performance. Nonetheless, the trade-off between the difficulty in 3D fabrication and high mixing performance need to be considered. Xia et al.
[56] proposed 3D passive micromixer designs operating at low Reynolds numbers.
The micromixers, known as two-layer crossing channel micromixers (TLCCMs),
were realized as TLCCM-model A and TLCCM-model B shown in Fig. 2.20.
Using laser ablation method, the micromixers were made of 1.5 mm thick transparent polymer poly (methyl methacrylate) plates. They found that chaotic advection
