Design and simulation study of obstacle based passive micromixer

Micromixer can be dividing by two categories which are active micromixer and passive micromixer. Due to simple fabrication technology and the easy implementation in a complex microfluidic system, obstacle based passive micromixers will be the focus of this project. Due to laminar flow (Reynold Nu...
