Abstract

We present results for the most stable contact angle using a numerical implementation of the tilting plate method of Montes et al. (Montes Ruiz-Cabello, F. J.; Rodriguez-Valverde, M. A.; Cabrerizo-Vilchez, M. Soft Matter 2011, 7, 10457-10461). Comparison with the experimental results is made, obtaining a good agreement in most situations. In addition, the evolution of the contact angles of a tilted drop with a fixed circular line is analyzed. This analysis allows one to theoretically predict the most stable contact angle for tilted drops.

摘要

我们使用蒙特斯等人（蒙特斯·鲁伊斯 - 卡贝略，F. J.；罗德里格斯 - 瓦尔韦德，M. A.；卡布雷里佐 - 维列斯，M.《软物质》2011年，7卷，10457 - 10461页）倾斜板法的数值实现方式，给出了最稳定接触角的结果。与实验结果进行了比较，在大多数情况下取得了良好的一致性。此外，分析了具有固定圆形边界的倾斜液滴接触角的演变。该分析使人们能够从理论上预测倾斜液滴的最稳定接触角。
