通过边缘流动的流体环和液滴阵列
Fluid rings and droplet arrays via rim streaming
摘要：
当从液滴尖端拉出的细线崩解时，尖端流产生微米和亚微米尺寸的液滴。在这里，我们报告流从赤道的一滴放在一个统一的电场。这种不稳定性会产生环绕液滴的同心流体环，这些流体环在赤道平面上破裂形成微滴阵列。我们表明，流的结果从界面的不稳定性在停滞线的电流体动力学流，这将创建一个尖锐的边缘。流动从边缘吸引一层薄薄的薄片，使流体圆柱体不稳定并脱落。这种流动现象为制备单分散微乳液提供了一条新的途径。
英文摘要：
Tip-streaming generates micron- and submicron- sized droplets when a thin thread pulled from the pointy end of a drop disintegrates. Here, we report streaming from the equator of a drop placed in a uniform electric field. The instability generates concentric fluid rings encircling the drop, which break up to form an array of microdroplets in the equatorial plane. We show that the streaming results from an interfacial instability at the stagnation line of the electrohydrodynamic flow, which creates a sharp rim. The flow draws from the rim a thin sheet which destabilizes and sheds fluid cylinders. This streaming phenomenon provides a new route for generating monodisperse microemulsions.
