The dynamics of a triangular magnetocapillary swimmer is studied using the lattice Boltzmannmethod. We extend on our previous work, which deals with the self-assembly and a specific type of theswimmer motion characterized by the swimmer’s maximum velocity centred around the particle’s inverseviscous time. Here, we identify additional regimes of motion. First, modifying the ratio of surface tensionand magnetic forces allows to study the swimmer propagation in the regime of significantly lower frequenciesmainly defined by the strength of the magnetocapillary potential. Second, introducing a constant magneticcontribution in each of the particles in addition to their magnetic moment induced by external fields leadsto another regime characterized by strong in-plane swimmer reorientations that resemble experimentalobservations. |
