T型微通道液滴/气泡生成时间和大小的研究现状

Review of Droplet/Bubble Formation Time and Size in T Junction Microchannel

利用微流体机械可以生成更均匀、大小可调的微液滴/气泡。文中分析了T型微通道生成微液滴/气泡的典型流型以及过程中的主要受力、微液滴形成/破碎过程的典型阶段以及相关的影响因素,总结了现有的利用力平衡方法预测微液滴/气泡大小的关系式,为有效控制T型微通道内微液滴/气泡的生成时间以及最终的体积,形成一种稳定的多相流流动提供了参考。

Micro droplets/bubbles with finer monodispersity and more controllable size can be formed by using microfluidic devices.This paper analyzed typical flow regime,the forces,the different phases and impact factors during droplets/bubbles formation in T junction microchannel.The prediction relations of micro droplets/bubbles formation time and final volume mainly by the method of force balance are summarized,which provide the reference to form the stable multiphase flow in T junction microchannels.
