Abstract

In this article, we designed a rhombic electroosmotic micromixer (REM). REM uses the principles of convergence and divergence in combination with microelectrodes to improve mixing efficiency. We improved the mixing efficiency by changing the rhombic angle and the combination of different rhombic elements. Then, the effects of electrode voltage, electrode configuration, Reynolds number, and AC frequency on the mixing performance were studied. The results show that the mixing efficiency of REM can exceed 99% when an asymmetric potential difference is applied in the channel, the AC voltage is 10 V and the electroosmotic micromixer has two sets of rhombic units.

摘要

在本文中，我们设计了一个菱形电渗微混合器 (REM)。REM 结合微电极使用收敛和发散的原理来提高混合效率。我们通过改变菱形角度和不同菱形元素的组合来提高混合效率。然后，研究了电极电压、电极配置、雷诺数和交流频率对混合性能的影响。结果表明，当通道中施加不对称电位差、交流电压为10 V、电渗微混合器具有两组菱形单元时，REM的混合效率可超过99%。
