Abstract

Capillary invasion of liquid is a spontaneous phenomenon that occurs at length scales smaller than the capillary length. By means of capillary action, numerous applications have been developed. We investigate the time-dependent displacement of a Newtonian oil using viscoelastic polyethylene oxide solutions. The setup implies a capillary tube in a horizontal configuration that was partially prefilled with oil. We emphasize the prefilling liquid’s role in the dynamics of the system and show the influence of the displacing liquid’s viscoelastic properties. We find significant changes in the capillary regime as the displacing liquid’s viscoelastic properties change.

利用粘弹性流体实现毛细管中的石油位移

毛细管侵入是一种自发现象，发生在小于毛细管长度的尺度上。利用毛细作用，开发了许多应用。我们使用粘弹性聚乙烯氧化物溶液研究牛顿油的时间相关位移。该装置暗示了一根水平配置的毛细管，其中部分预充有油。我们强调了预充液在系统动力学中的作用，并展示了顶替液粘弹性特性的影响。我们发现，随着置换液体粘弹性的改变，毛细管状态也发生了显著的变化。
