Comparison of mixing performance and mixing efficiency per mm mixing path length, at Re = 70, evaluated numerically in SeLMA and a selection of micromixers adapted from literature: the Archimedes spiral [19], the Meandering-S [18], and a T-Channel.

Micromixer	η (%)	$\frac{\eta }{L}(\%/\mathrm{mm})$
SeLMA	87.015	6.8911
Meandering-S	72.31	6.02
Archimedes	63.80	5.32
T-Channel	19.11	1.59
