这份报纸与集体转移在一台同轴的 microfluidic 设备论述液体液体 microflows 的试验性的结果。三个工作系统是 n-butanol + 磷的酸(PA )+ 水,甲基异丁基酉同类(MIBK )+PA + 水,在 tri-n-butylphosphate (TBP ) 的 30% 煤油 +PA + 水。集体转移的方向和紧张被在二个阶段之一增加 PA 调整相互预先浸透了。当 PA 从器官的阶段转了到水的阶段时,微小的水的微滴可以由集体转移动机在器官的阶段内产生在一些特殊情况上直接形成一个新 W/O/W 流动模式。一旦 PA 集中很高,强烈 Marangoni 效果能被观察作为尾巴从微滴扔器官的阶段的部分。PA 的分裂期间转移能扩展 jetting 流动区域,特别地为有低或中等的界面的紧张的系统并且当集体转移方向从水的阶段到器官的阶段时。
This paper presents the experimental results of liquid-liquid microflows in a coaxial microfluidic device with mass transfer. Three working systems were n-butanol + phosphoric acid (PA) + water, methyl isobutyl ketone (MIBK) + PA + water, 30% kerosene in tri-n-butylphosphate (TBP)+ PA + water. The direction and intensity of mass transfer were adjusted by adding PA in one of two phases mutual saturated in advance. When PA transferred from the organic phase to the aqueous phase, tiny aqueous droplets may generate inside the organic phase by mass transfer inducement to form a new W/O/W flow pattern directly on some special cases. Once the PA concentration was very high, violent Marangoni effect could be observed to throw part of organic phase out of droplets as tail. The interphase transfer of PA could expand the jetting flow region, in particular for systems with low or medium interfacial tension and when the mass transfer direction was from the aqueous phase to the organic phase.
