摘　　要：微流控混合芯片是微流控芯片系统中的重要组成部分,其混合效率直接影响后续反应产物的分布和反应体系的容量.文中对基于电渗流驱动的微流控混合芯片的系统级建模技术进行了研究,本研究首先结合基于电渗流驱动的微流控混合芯片的控制方程,对系统各组件的参数化行为模型进行了提取,在此基础上编程实现了系统各组件的多端口组件模型,构建了基于电渗流的微流控混和芯片系统级模型,模型仿真结果与有限元方法相比,相对误差为2.5%,而仿真速度却远远高于有限元方法.表明该方法在不显著损失系统精度的前提下,可以更加有效的对系统性能做出评价.Microfluidic mixer is an important part of the microfluidic control system. The effect of the microfluidic mixer on other part of the microfluidic control system reflects on as reaction and seperation. This paper presents a system level modeling for electrokinetic passive micromixers. The parameterized behavior models was developed based on the control function of electrokinetic passive micromixers. Then the multi-port element was coded with hardware description language MAST based on the parameterized behavior models. The validity of the parameterized behavior models is illustrated with the system level simulation of a simple electrokinetic passive micromixer. Simulation result shows that the parameterized behavior models of this paper is agree well with t finite element analysis, and the model is effective for rapidly performing system-level simulation.
