Bas-relief micromixers

Figure4.44 Bas-relief micromixer with microstructured ramps in the channel floor and ceiling, termed caterpillar micromixer (by courtesy of IMM).

Bas-relief micromixers induce transversal motion, when miscible liquids are considered, to mix by convection [92,93]. In the gas-liquid case to be considered here, the mechanism for bubble formation is yet unclear, but likely related to shear forces coming from a similar liquid motion in the dispersed flow. Caterpillar mixers induce such transversal motion by ramp-like microstructures, lifted up and down, placed in one channel at the bottom and ceiling [4] (see also Ref. [S6]). Caterpillar mixers were developed as family of devices with grouped capacity using smart enlargement of the internal chaimel and have high volume flows, for example,...
