论文摘要
进行了三维模拟，并进行了完全分辨的流体动力学，以研究重力下单个蠕动器的动力学，以阐明其在平板附近的运动。出现不同的动力学，以获得不同的重力强度。在适度的重力状态下，中性蠕动的人和拉特人最终停止在垂直于板的方向上移动和重新定向。相反，推动器朝着倾斜的方向表现出连续运动。在强大的重力状态下，所有类型的蠕动沉积物和垂直于板的重新定向。在这项研究中，引入了手性，以模拟现实的微型武器，并提出了其对游泳运动员动力学的关键作用。
Three-dimensional simulations with fully resolved hydrodynamics are performed to study the dynamics of a single squirmer under gravity, in order to clarify its motion in the vicinity of a flat plate. Different dynamics emerge for different gravity strengths. In a moderate gravity regime, neutral squirmers and pullers eventually stop moving and reorient in a direction perpendicular to the plate; pushers, instead, exhibit continuous motion in a tilted direction. In the strong gravity regime, all types of squirmers sediment and reorient perpendicularly to the plate. In this study, the chirality is introduced to model realistic micro-swimmers, and its crucial effects on the swimmer dynamics are presented.
