论文摘要
我们研究了不同表面紧张局部另一个液体内部液态的破裂。通常，液态螺纹的捏合受流体流动的动力学控制。但是，当界面张力是超低的（比正常液体低2至3个阶）时，我们发现捏合动力学可以由大量扩散控制。通过研究捏合的速度和轮廓，我们解释了为什么以扩散为主的捏合接管了超低表面紧张局部的常规分裂。
We study the breakup of a liquid thread inside another liquid at different surface tensions. In general, the pinch-off of a liquid thread is governed by the dynamics of fluid flow. However, when the interfacial tension is ultralow (2 to 3 orders lower than normal liquids), we find that the pinch-off dynamics can be governed by bulk diffusion. By studying the velocity and the profile of the pinch-off, we explain why the diffusion-dominated pinch-off takes over the conventional breakup at ultralow surface tensions.
