Abstract

We investigated the synchronization phenomena of the oscillatory flows in two parallelly connected Starling resistors, which are an ideal model system of two coupled collapsible tubes merging into a single tube downstream. The stable synchronization modes depended on the distance between the deformable region and the merging point; only an in-phase mode was stable for the large distance, in-phase and anti-phase modes were bistable for the middle distance, and again only an in-phase mode was stable for the small distance. An anti-phase mode became stable through the subcritical pitchfork bifurcation by decreasing the distance. Further decreasing the distance, the anti-phase mode became unstable through the subcritical Neimark-Sacker bifurcation. We also clarified the distance dependence of the amplitude and frequency for each stable synchronization mode.
同步振荡流在两个并联的斯特林电阻
本文研究了两个平行连接的Starling电阻中振荡流的同步现象,这是一个理想的双耦合可折叠管下游合并成单管的模型系统。稳定同步模式取决于可变形区域与合并点之间的距离;在大距离范围内,只有同相模式是稳定的;在中距离范围内,只有同相模式和反相模式是双稳定的;在小距离范围内,只有同相模式是稳定的。反相模型通过亚临界干草叉分叉通过减小距离变得稳定。进一步减小距离,反相模式通过亚临界neimmark - sacker分岔变得不稳定。我们还澄清了每个稳定同步模式的振幅和频率的距离依赖关系。
