Marina Pasquet, François Boulogne, Frédéric Restagno, Emmanuelle Rio

AI总结:

本文研究垂直巨型肥皂膜寿命,发现相对湿度和尺寸影响显著,排水影响小,蒸发主导,Boulogne & Dollet模型可预测最大寿命。

摘要:

我们研究了矩形垂直肥皂膜的寿命,并探讨了相对湿度以及两个尺寸对大型肥皂膜稳定性的影响,这些膜的高度可达1.2米。利用自动破裂检测系统,我们对其寿命进行了稳健的统计测量,同时测量了膜的变薄动力学。我们证明,与蒸发相比,排水对膜的稳定性影响可忽略不计。为此,我们将测量的寿命与Boulogne & Dollet模型\ref{BoulogneDollet2018}的预测进行比较,该模型最初用于描述水凝胶的对流蒸发。有趣的是,我们表明该模型可以预测所有尺寸下膜的最大寿命。

英文摘要:

We consider the lifetime of rectangular vertical soap films and we explore the influence of relative humidity and both dimensions on the stability of large soap films, reaching heights of up to 1.2 m. Using an automated rupture detection system, we achieve a robust statistical measurement of their lifetimes and we also measure the film thinning dynamics. We demonstrate that drainage has a negligible impact on the film stability as opposed to evaporation. To do so, we compare the measured lifetimes with predictions from the Boulogne \& Dollet model \cite{BoulogneDollet2018}, originally designed to describe the convective evaporation of hydrogels. Interestingly, we show that this model can predict a maximum film lifetime for all sizes.
