| 摘 要： | 对于许多微流体装置来说，流体的混合是至关重要的。为了实现微流体混合控制，对基于电磁流体动力学原理的微流道主动混合控制方法进行了研究。该方法中使用了一个混合室，在动态洛伦兹力的作用下，混合室内流体往复周期的运动。流体速度的周期性变化使流体分界面折叠，从而使流体接触面增加。用CCD记录设备记录了流体的快速混合过程，并对流体的混合程度进行定量分析。

| Abstract: | Mixing is important and critical for most microfluidics devices. An active mixing method based on magneto hydrodynamic theory is studied for microchannel flow mixing control. A mixing chamber is used for the microchannel flow mixing. The dynamic Lorentz force acted on the fluids causes them to move back and forth periodically in the chamber. The periodically changed velocity causes the interface between fluids folded and the interracial areas increase. The repeat movement and the folding of the interface make the fluids mixed. Rapidly mixing process is recorded and the mixing performance is evaluated. |
