ABSTRACT

We present Surface Evolver computer simulations for two-dimensional (2d) foams in which the contact angle at which liquid films and Plateau borders meet is non-zero. We determine the average coordination number Z of bubbles over a wide range of finite contact angles θ and liquid fractions ϕ. We find a linear scaling of Z for values of ϕ between about 0.07 and 0.15, corroborating previous data obtained for the case of zero contact angle. The results highlight the importance of attractive bubble interactions for 2d foams.

有限接触角二维泡沫的平均配位数随液体分数的变化

摘要

我们介绍了二维（2d）泡沫的Surface Evolver计算机仿真，其中液膜和高原边界相遇的接触角不为零。我们确定平均配位数ž气泡的在宽范围内的有限的接触角θ和液体馏分φ。我们找到的线性缩放ž为值φ介于约0.07和0.15之间，证实为零接触角的情况下获得的先前数据。结果强调了有吸引力的气泡相互作用对于2d泡沫的重要性。
