A Numerical Study on Electro-osmotic Flow and Stirring Characteristics in a Microchannel with Local Adjustment of Electric Potential

마이크로 채널 내 국소적 전위 인가에 따른 전기삼투 유동 및 혼합 특성에 대한 수치해석적 연구

In this study a newly designed electro-osmotic micro-mixer is proposed. This study is composed of a channel and metal electrodes attached locally on the side wall surface ultimately to control the mixing effect. To obtain the flow patterns, numerical computation was performed by using a commercial code, CFD-ACE. The fluid-flow solutions are the cast into studying the characteristics of stirring in terms of the mixing index. It was shown that the local control of the electric potential can indeed contribute to the enhancement of mixing effect.
