SAR micromixer [57]
SAR design with repeating two-layer O- and X-shaped units shown in Fig. 2.22.
The micromixer achieved complete mixing over a short mixing length of 1.5 mm.
The high mixing performance of the micromixer was attributed to saddle-shaped flow
structure which promoted chaotic advection. These 3D micromixers [56–58] showed
high mixing performances over a wide Reynolds number range, and significantly
