Design of Passive Micromixers using the COMSOL Multiphysics software package
Published in 2008
Relief patterning of the surface of microchannels has been actively pursued as a method of promoting mixing in systems with a low Reynold’s number (<<100).
In this work, we explore, by using the COMSOL Multiphysics package and its Chemical Engineering Module, the possibility of enhancing the mixing quality of two fluids in a microchannel with a non-periodic fractal pattern of ridges on the channel bottom.
For the binary fluid system, we compare the mixing performance of channels with ridge locations determined by employing a Weierstrass fractal function, to the performance of staggered herring bone designs.
