W. Ehrfeld et al., Characterization of mixing in micromixers by a test reaction: Single mixing units and mixer arrays, IND ENG RES, 38(3), 1999, pp. 1075-1082
The mixing quality of a single mixing unit and mixer arrays having various
designs was characterized. A known test reaction for mixing quality had to
be optimized, since a much higher sensitivity as for the characterization o
f macroscopic mixers was needed. This adapted test reaction allowed not onl
y the characterization of the mixing quality but also analysis of the homog
eneity of the flow distribution between parallely aligned mixing units. A c
omparison of the mixing quality to those of macroscopic reference systems (
like mixing in stirred and unstirred vessels as well as to laminar and turb
ulent mixing-tees) is presented. The mixing quality-volume flow dependence
revealed a complex behavior, the hydrodynamic origin of which has been anal
yzed.
