Abstract :
A novel microfluidic mixing device for microsystems with electroosmotic flow (EOF)-driven liquid pumping is proposed and examined numerically. Previously demonstrated microchannel structure is considered, and the effect of various parameters have been examined numerically. The numerical results confirms the importance of effectively creating lateral velocity component in the microchannel. The results also suggest design information of the length, position and material of channel wall patterning for maximizing mixing enhancement effect.
