摘要

这项工作的重点是应用离子浓度极化现象来设计和研究一种电渗微泵模型。对离子浓度极化产生电渗流和泵效应的方式进行了数值研究。扩展空间电荷层的形成和电场对该电荷层的作用被应用于产生电渗透流，以驱动系统中的流动。通过改进几何配置，可以增强泵送效果。我们进行了多次模拟，以获得最佳的微泵设计。

A numerical study on applying ion concentration polarization in micropump design

This work focuses on applying the phenomenon of ion concentration polarization to design and investigate a micropump model that is a kind of electroosmotic micropump. Numerical study is conducted for ion concentration polarization in the manner that generates electro-osmosis flow and pumping effect. The formation of the extended space charge layer and the actions of the electric field upon this layer is applied to generate electro-osmosis flow to drive flow in the system. It is clarified that pumping effect can be enhanced by improving the geometry configurations. Multiple simulations are conducted to obtain an optimal micropump design.
