论文摘要
单个或微武器的集合的性能很大程度上取决于其成分和本身之间的流体动力耦合。我们提出了基于晶格Boltzmann方法（LBM）仿真的单个和一对微晶状体的数值研究。我们的数值算法由两个可分离的部分组成。 Lagrange多项式提供了Microswimmers的离散化，晶格Boltzmann方法捕获了周围流体的动力学。两个组件通过浸没的边界方法夫妇。我们提供了单个游泳器系统的数据，我们的数据还显示了集体效应的开始，尤其是游泳者群集的总体速度增加。
The performance of a single or the collection of microswimmers strongly depends on the hydrodynamic coupling among their constituents and themselves. We present a numerical study for a single and a pair of microswimmers based on lattice Boltzmann method (LBM) simulations. Our numerical algorithm consists of two separable parts. Lagrange polynomials provide a discretization of the microswimmers and the lattice Boltzmann method captures the dynamics of the surrounding fluid. The two components couple via an immersed boundary method. We present data for a single swimmer system and our data also show the onset of collective effects and, in particular, an overall velocity increment of clusters of swimmers.
