From: Optimization of passive micromixers: effects of pillar configuration and gaps on mixing efficiency

Demonstration of the flow pattern and mixing efficiency with respect to the pillar diameter (Dp) in the slanted configuration. Streamlines passing through the pillars for (A) \(D_{p} = 125\;\upmu{\text{m}}\) and (B) \(D_{p} = 50 \;\upmu\text{m}\). Dye concentration for (C) \(D_{p} = 125\;\upmu{\text{m}}\) and (D) \(D_{p} = 50\;\upmu{\text{m}}\). Magnified view of the velocity vectors through the pillars for (E) \(D_{p} = 125\;\upmu{\text{m}}\) and (F) \(D_{p} = 50 \;\upmu\text{m}\). The reference vectors (green) show 0.1 m/s.
