摘要:

本文研究了位于垂直振动刚性平面上的不可压缩粘性流体层的动力学问题,其上边界由自由面给出。我们考虑水平周期流的重力和表面张力问题。这个问题产生了平坦但垂直振荡的平衡解,本文的主要目的是研究这些平衡在某些参数区域的渐近稳定性。我们证明,有和没有表面张力存在一个参数制度,其中足够小的扰动在时间$t = 0$的平衡引起的全球时间的解决方案,以确定的定量率衰减到平衡。

英文摘要:

This paper concerns the dynamics of a layer of incompressible viscous fluid lying above a vertically oscillating rigid plane and with an upper boundary given by a free surface. We consider the problem with gravity and surface tension for horizontally periodic flows. This problem gives rise to flat but vertically oscillating equilibrium solutions, and the main thrust of this paper is to study the asymptotic stability of these equilibria in certain parameter regimes. We prove that both with and without surface tension there exists a parameter regime in which sufficiently small perturbations of the equilibrium at time $t = 0$ give rise to global-in-time solutions that decay to equilibrium at an identified quantitative rate.
