Abstract

We propose a model for the structure formation of jellyfish swimming based on active Brownian particles. We address the phenomena of counter-current swimming, avoidance of turbulent flow regions and foraging. We motivate corresponding mechanisms from observations of jellyfish swarming reported in the literature and incorporate them into the generic modelling framework. The model characteristics is tested in three paradigmatic flow environments.

摘要

我们提出了一个基于活性布朗粒子的水母游动结构形成模型。我们解决了逆流游动、避免湍流区域和觅食等现象。我们从文献中报道的水母群集观察中得到了相应的机制，并将其纳入通用建模框架中。该模型的特点在三个典型的流动环境中进行了测试。
