在交流电渗流(ACEO)泵的研究中,一般忽略电极厚度的影响;而三维交流电渗流泵通过将电极厚度设计成台阶形式后,可以大大提高电渗流泵的流量。数值研究了电极台阶高度对三维交流电渗流泵流量的影响。研究发现:在驱动电压幅值不变的条件下,随着台阶高度的增加,三维交流电渗流泵流量也会增大;而当台阶高度增加到一定程度后,流量又会随着台阶高度的增加而减小。因此,在三维交流电渗流泵的设计制造中,需要优化电极的台阶高度,选择合适的台阶高度可以极大地提高电渗流泵的流量。通过和传统交流电渗流泵的比较,还研究了三维交流电渗流泵对流量的增强效果。结果表明:在相同模型尺寸参数下,优化台阶高度后的三维交流电渗流泵能极大提高流量。
In the research of ACO pump, the influence of electrode thickness is generally neglected. However, the flow of the electroosmotic flow pump can be greatly improved by designing the electrode thickness into a step form in the three-dimensional AC pump. The effect of electrode step height on the flow rate of three-dimensional AC seepage pump was numerically investigated. The results show that with the increase of the step height, the flow rate of the three-dimensional AC seepage pump will also increase under the condition of the same driving voltage amplitude. When the step height increases to a certain extent, the flow rate will increase with the increase of the step height And reduce. Therefore, in the design and manufacture of 3D AC pumps, the height of the electrodes needs to be optimized. Choosing the appropriate height of the steps can greatly improve the flow of the electroosmotic pump. Compared with the traditional AC seepage pump, the effect of three-dimensional AC seepage pump on the flow rate is also studied. The results show that under the same model size parameters, the three-dimensional AC pump with optimized height can greatly improve the flow rate.
