Numerical Study and Comparison of Passive Mixing in Helical Micromixers
Abstract: A passive mixing inside three micromixers has been studied with water as the mixing fluid. Since the mixing at the micro-level is governed by species diffusion hence it is a time-consuming process that requires an extended length of micromixer for the required amount of mixing. The present study tackles this problem by introducing two helical micromixers, a Three-dimensional helical micromixer (TDHM), and TDHM having four inlets (TDHM-FO). These micromixers need …
