Abstract

Flow through a narrow bent channel may induce topological rearrangements in a two-dimensional monodispersed dry liquid foam. We use the Cellular Potts Model to simulate a foam under a variable driving force in order to investigate the strain-rate response from these rearrangements. We observe a set of foams' behaviors ranging from elastic, viscoelastic to fluid regime. Bubble's topological rearrangements are localized and their cumulative rearrangements change linearly with time, thus nonavalanches critical behavior is found. The strain-rate affects the rate of topological rearrangements, its dependence on the drag force is nonlinear, obeying a Herschel–Bulkley-like relationship below the foam's flow point.
干有序泡沫的拓扑重排及流动模拟
在二维单分散干液泡沫中,通过狭窄弯曲通道的流动可引起拓扑重排。为了研究这些重排的应变率响应,我们使用细胞波模型模拟了一个可变驱动力下的泡沫。我们观察了泡沫从弹性、粘弹性到流体状态的一系列行为。气泡的拓扑重排是局部的,其累积重排随时间线性变化,从而发现了非雪崩临界行为。应变速率影响拓扑重排速率,其对阻力的依赖是非线性的,在泡沫的流点以下服从herschel - bulkley关系。
