“…This represents one of the most important areas in the process intensification concept. The microscale applications benefit from the miniaturization of the unit-building channels in which the characteristic lengths reach the values typical for boundary layers. − A number of micromixers and microreactors have been designed, attracting increasing attention of both industry and academia. − Furthermore, a considerable variety of novel micromixer concepts have been proposed, such as interdigital micromixer, split-and-recombine micromixer, micromixer based on the collision of microsegments, multifunctional micromixer, which makes use of alternating current electroosmotic flow and asymmetric electric field, packed-bed microreactors, ,, etc. However, because of their complex structures, manufacturing of these micromixers is difficult, and their practical application is limited.…”
