Characterization of Mixing in Micromixers by a Test Reaction: Single Mixing Units and Mixer Arrays
TL;DR: In this paper, the mixing quality of a single mixing unit and mixer arrays having various designs was characterized and a known test reaction for mixing quality had to be optimized, since a much higher sensitivity as for the characterization of macroscopic mixers was needed.
Journal ArticleDOI
An optimised split-and-recombine micro-mixer with uniform ‘chaotic’ mixing
TL;DR: A second generation micro-mixer, being a further optimised version of a first prototype, relying on the consequent utilisation of the split-and-recombine principle is presented, and it is shown that the mixing can be characterized by a positive finite-time Lyapunov exponent although being highly regular and uniform.
Journal ArticleDOI
Direct fluorination of toluene using elemental fluorine in gas/liquid microreactors

TL;DR: In this paper, a falling film microreactor and a micro bubble column were used for direct fluorination of toluene, pure or dissolved in either acetonitrile or methanol, using elemental fluorine in gas/liquid microreactors.
Journal ArticleDOI
Gas-liquid and gas-liquid-solid microstructured reactors : contacting principles and applications
TL;DR: A variety of gas-liquid microchannel reactions have been developed so far, using different contacting principles as discussed by the authors, such as segmented (Taylor) flow in a single microchannel or numbered-up versions such as the microbubble column; other flow patterns such as annular flow may be achieved as well.
Journal ArticleDOI
Laminar mixing in different interdigital micromixers: I. Experimental characterization
TL;DR: In this article, three interdigital type glass micromixers with alternating feed channels to periodically create liquid multilamellae, were fabricated for basic investigations of hydrodynamics for liquid mixing of two streams.
