Novel Compact Mesh Structure Micromixer with Multiple Outlets for Generation of Concentration Gradients

A novel micromixer concept for generation of concentration gradients, inspired by a Chinese design, the traditional Chinese knot “中国结,” which features a core mesh structure allowing for a very compact design, is presented. The new concept has been designed using modern computer-aided design (CAD) and computational fluid dynamics (CFD) simulation software and validated by performing multiple experiments. The final design is found to be significantly more compact than conventional ones and allows the use of up to 15 outlet channels.
