【摘要】 根据介质上电润湿的基本理论,利用计算流体动力学软件CFD-ACE+,成功模拟出了典型的“三明治“结构数字微流控器件中水滴输运、产生、分离和合并的全过程。模拟结果显示,上下极板间距和液滴输运速度之间呈线性关系;并且,当极板间距大于200μm时,液滴分离容易失败。模拟结果与已有的实验结果符合的非常好。更多还原

【Abstract】 Based on the fundamental theory of EWOD and with the help of computational fluid dynamics(CFD) software,CFD-ACE+,the processes of transporting,creating,dividing and merging droplets of water in the digital microfluidic device with a typical Sandwich structure are simulated successfully.The linear relation between the gap height and the droplet movement speed is obtained.When the gap height is larger than 200μm,it becomes much more difficult to split the droplet.The simulation results agree quite well with the experimental findings.更多还原
