Abstract

The dynamics of a triangular magnetocapillary swimmer is studied using the lattice Boltzmann method. We extend on our previous work, which deals with the self-assembly and a specific type of the swimmer motion characterized by the swimmer's maximum velocity centred around the particle's inverse viscous time. Here, we identify additional regimes of motion. First, modifying the ratio of surface tension and magnetic forces allows to study the swimmer propagation in the regime of significantly lower frequencies mainly defined by the strength of the magnetocapillary potential. Second, introducing a constant magnetic contribution in each of the particles in addition to their magnetic moment induced by external fields leads to another regime characterized by strong in-plane swimmer reorientations that resemble experimental observations.

摘要

使用晶格玻尔兹曼方法研究了三角形磁毛细游泳者的动力学。我们扩展了我们之前的工作，该工作涉及自组装和游泳者运动的特定类型，其特征在于游泳者的最大速度围绕颗粒的反向粘性时间集中。在这里，我们确定了其他运动状态。首先，通过改变表面张力和磁场力的比值，可以研究游泳者在主要由磁毛细势强度定义的频率明显较低的情况下的传播。其次，在每个粒子中除了由外部场引起的磁矩之外引入恒定磁场贡献，导致另一种以强烈的平面内游泳者重新定向为特征的状态，类似于实验观察。
