In this paper, we have designed a Koch fractal electroosmotic micromixer (KFEM). A low-voltage electroosmotic micromixer. In order to optimize the electrode position, Koch microchannel is designed according to the Koch fractal principle and the electrode pairs based on the fractal are arranged. Then the effect of electrode voltage, electrode distribution positions, the number of electrode pairs, two kinds of Koch fractal structures, Reynolds (Re) number and the frequency of alternating current (AC) on the mixing performance are studied. The results show that the mixing efficiency can reach 99% in a short time when the AC voltage is 1 V, the AC frequency is 12 Hz and the electroosmotic micromixer has two sets of electrode pairs.

具有科赫分形结构的电渗微混合器的混合性能

在本文中，我们设计了一个Koch分形电渗微混合器（KFEM）。低压电渗微混合器。为了优化电极位置，根据科赫分形原理设计了科赫微通道，并排列了基于分形的电极对。然后研究了电极电压，电极分布位置，电极对数，两种科赫分形结构，雷诺数（Re）和交流频率（AC）对混合性能的影响。结果表明，当交流电压为1 V，交流频率为12 Hz且电渗微混合器有两组电极对时，混合效率可在短时间内达到99％。
