Paper Title:
Mixing Enhancement of a Passive Micromixer by Applying Boundary Protrusion Structures
  Abstract

The purpose of this study is to examine the mixing behavior of two test fluids flowing via a passive micromixer with protruded structures arranged at the boundary of the mixer. In the analysis, the theoretical model was based on the three-dimensional conservation equations of mass, momentum and species concentration; whereas, the governing equations were numerically solved by using an iterative SIMPLEC algorithm to resolve flow/transport properties. The predicted mixing efficiency at different axial locations was compared with available measured results in the literature for code validation. Numerical experiments were extended to study the shape effect of boundary protrusion structures on mixing enhancement of a passive micromixer with diamond-shaped obstructions.
