柔性膜上水性泡沫的生长

Growth of aqueous foam on flexible membranes

Hiroyuki Shima

摘要:

本文研究了可变形膜夹持下二维干泡沫的粗化动力学。时变变形的限制膜引起的多边形细胞的气泡的演变相比,刚性膜的情况下,一个显着的改变。这种变化是由于细胞间的气体传输速率和细胞域内的表面曲率的时间波动之间的相关性。参考现有的材料常数来理解相关效应对人工控制粗化动力学的实用性。

英文摘要:

In this paper, I study the coarsening dynamics of two-dimensional dry foam sandwiched by deformable membranes. The time-varying deformation of the confining membranes gives rise to a significant alteration in the evolution of polygonal cells of bubbles when compared to the case of rigid membranes. This alteration is attributed to the correlation between the rate of inter-cell gas transfer and temporal fluctuation in surface curvature within a cell domain. The existing material constants are referred to understand the utility of the correlation effect toward the artificial control of the coarsening dynamics.
