Abstract

We study the spatial patterns formed by interacting populations or reacting chemicals under the influence of chaotic flows. In particular, we have considered a three-component model of plankton dynamics advected by a meandering jet. We report general results, stressing the existence of a smooth-filamental transition in the concentration patterns depending on the relative strength of the stirring by the chaotic flow and the relaxation properties of planktonic dynamical system. Patterns obtained in open and closed flows are compared.

反应物质的混沌平流:浮游生物在蜿蜒射流上的动力学
我们研究在混沌流的影响下由相互作用的种群或化学反应形成的空间格局。特别地,我们考虑了浮游生物动力学的一个三组分模型,由一个蜿蜒的射流平流。我们报告了一般结果,强调在浓度模式中存在一个平滑的丝状过渡,这取决于混沌流搅拌的相对强度和浮游动力系统的弛豫特性。比较了在开放流和封闭流中得到的模式。
