斜面下的Rayleigh-Taylor不稳定性

Rayleigh-Taylor instability under an inclined plane

P. -T Brun, Adam Damiano, Pierre Rieu, Gioele Balestra, François Gallaire

摘要:

我们重新审视了典型的瑞利-泰勒不稳定性,并研究了斜面底面上的流体薄膜的情况。沿平面的自然流动的存在与传统的液滴形成不稳定性相竞争。特别地,实验揭示,对于大于临界值的倾斜,没有液滴形成。这些功能是合理的,在本文中进行的绝对/对流分析的上下文中。

英文摘要:

We revisit the canonical Rayleigh-Taylor instability and investigate the case of a thin film of fluid upon the underside of an inclined plane. The presence of a natural flow along the plane competes with the conventional droplet forming instability. In particular, experiments reveal that no drops form for inclinations greater than a critical value. These features are rationalized in the context of the absolute/convective analysis conducted in this article.
