将流动聚焦几何结构集成到微流体装置中，用于研究液-液系统中的液滴形成。相图显示了液滴尺寸作为两种液体的流速和流速比的函数，包括一种状态，其中液滴尺寸与孔口宽度相当，以及第二种状态，其中液滴尺寸由细“聚焦”线的直径决定，因此形成比孔口小得多的液滴。可以生产单分散和多分散乳液。 (C) 2003 年美国物理研究所。
A flow-focusing geometry is integrated into a microfluidic device and used to study drop formation in liquid-liquid systems. A phase diagram illustrating the drop size as a function of flow rates and flow rate ratios of the two liquids includes one regime where drop size is comparable to orifice width and a second regime where drop size is dictated by the diameter of a thin "focused" thread, so drops much smaller than the orifice are formed. Both monodisperse and polydisperse emulsions can be produced. (C) 2003 American Institute of Physics.
