System Simulations of Complex Electrokinetic Passive Micromixers

Keywords: , , ,

This paper presents a composable system simulation framework using an analog hardware description language implementing behavioral models for electrokinetic micromixers that are capable of accurately capturing the effects of mixer topology/geometry, flow ratio and material properties on the mixing performance. The accuracy (relative error less than 8%) and tremendous speedup (10~10, 000 X) of the simulations are verified by comparison with experiments and numerical studies. Beyond previous work, this paper presents models of variable cross-sectional mixing channel and width-wise diverging intersections that can be used for quantitative evaluation of the influence of mixing channel geometry on the sample mixing and the more complex topologies such as split-and-recombine mixer and serial mixing networks by comparison with numerical and experimental data.
