摘要

我们提出了具有镜面边界条件的无限长圆柱域中 Cucker-Smale-Stokes 系统弱解的全局存在性。所提出的系统由动力学 Cucker-Smale 模型和斯托克斯系统组成，分别用于无限长圆柱形域中的成群粒子和不可压缩流体。它模拟了流体-粒子-结构相互作用产生的集体动力学。对于这个模型，我们提供了一个弱解的全局存在性，并通过数值模拟展示了成群粒子的集体行为。

On the Interactions of Flocking Particles with the Stokes Flow in an Infinite Channel

We present the global existence of weak solutions to the Cucker–Smale–Stokes system in an infinitely long cylindrical domain with the specular boundary condition. The proposed system consists of the kinetic Cucker–Smale model and the Stokes system for flocking particles and an incompressible fluid, respectively, in an infinitely long cylindrical domain. It models the collective dynamics resulting from the fluid-particle-structure interactions. For this model, we provide the global existence of a weak solution and numerical simulations that exhibit collective behaviors of flocking particles.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
