非常Viscous Fluid引流过程中的自由表面变形和尖端形成

Free Surface Deformation and Cusp Formation During the Drainage of a Very Viscous Fluid

Sahraoui Chaieb

摘要:

我们报告了一个非常粘滞的流体的自由表面的变形的实验研究时排出的容器通过一个圆形孔。在流体的某个临界高度处,自由表面变形并形成凹坑。后来,这个酒窝变成了一个尖点。我们发现,从槽底测量的凹坑高度以及在尖点形成之前凹坑的曲率遵循幂律行为。我们发现,这种行为是由于粘性压力和表面张力之间的相互作用

英文摘要:

We report an experimental study of the deformation of the free surface of a very viscous fluid when drained out of a container through a circular orifice. At some critical height of the fluid, the free surface deforms and forms a dimple. At later times, this dimple becomes a cusp. We found that the height of the dimple measured from the bottom of the tank as well as the curvature of the dimple before the cusp formation, follows power laws behaviors. We found that this behavior was due to an interplay between viscous pressure and surface tension
