稳定化Kuramoto-Sivashinsky方程:实验一维胞状流二次不稳定性和相关动力学的有用模型

Stabilized Kuramoto-Sivashinsky equation: A useful model for secondary instabilities and related dynamics of experimental one-dimensional cellular flows

P. Brunet

摘要:

我们报告的数值模拟稳定的Kuramoto-Sivashinsky方程的一维细胞的解决方案。这个方程提供了一系列运动界面的模式形成不稳定性的一般行为,例如一系列二次不稳定性或向无序的过渡。我们将这些集体行为与实验中观察到的行为进行了比较。特别是,分叉状态的不稳定的情况下,研究了空间半扩展的情况下,这是常见的现实模式,但几乎没有探索到目前为止。

英文摘要:

We report numerical simulations of one-dimensional cellular solutions of the stabilized Kuramoto-Sivashinsky equation. This equation offers a range of generic behavior in pattern-forming instabilities of moving interfaces, such as a host of secondary instabilities or transition toward disorder. We compare some of these collective behaviors to those observed in experiments. In particular, destabilization scenarios of bifurcated states are studied in a spatially semi-extended situation, which is common in realistic patterns, but has been barely explored so far.
