Computational fluid dynamics and experimental investigations on liquid-liquid mass transfer in T-type microchannels with different mixing channel barrier shapes

Micromixers with different shapes of barriers including cylindrical, semi-cylindrical, conical, and semi-conical were fabricated using 3D printer. Water (Alizarin Red S) + Aliquat 336 + 1-octanol system was chosen for analyzing mass transfer. Computational fluid dynamics analysis showed that the imp...

Description
Summary:Micromixers with different shapes of barriers including cylindrical, semi-cylindrical, conical, and semi-conical were fabricated using 3D printer. Water (Alizarin Red S) + Aliquat 336 + 1-octanol system was chosen for analyzing mass transfer. Computational fluid dynamics analysis showed that the improvement of flow patterns in the case of cylindrical barrier was higher than that in other micromixers. The extraction efficiency using cylindrical barriers was 23.7-83.7% higher than that of the plain one. Performance ratio criterion was used for design selection. The highest performance ratios with the values of 1.04-1.65 were obtained in the microchannel with six conical barriers.
