我们用高速光学成像技术研究了自由漂浮近晶气泡的动力学。大小从几百微米到几厘米的气泡是从塌陷的链状物中制备出来的。它们代表了在可控条件下研究薄膜流体动力学的理想模型系统。由于内部的近晶层结构,气泡在其独特的形状动力学中结合了肥皂膜和泡囊的特征。夹断后,它们从强拉长的初始形状向球形平衡松弛,首先是近晶层的缓慢重新分布,最后是微弱的、受阻的形状振荡。此外,我们还描述了自由漂浮的近晶气泡的破裂,以及近晶细丝的形成和稳定。
We have investigated the dynamics of freely floating smectic bubbles using high-speed optical imaging. Bubbles in the size range from a few hundred micrometers to several centimeters were prepared from collapsing catenoids. They represent ideal model systems for the study of thin-film fluid dynamics under well-controlled conditions. Owing to the internal smectic layer structure, the bubbles combine features of both soap films and vesicles in their unique shape dynamics. From a strongly elongated initial shape after pinch-off, they relax towards the spherical equilibrium, first by a slow redistribution of the smectic layers, and finally by weak, damped shape oscillations. In addition, we describe the rupture of freely floating smectic bubbles, and the formation and stability of smectic filaments.
