我们提出了一种在低雷诺数流中游泳的方法，该方法基于人工纤毛的磁驱动微游泳者的纤毛运动。通过求解磁力-弹性-流体动力学耦合问题，我们证明了纤毛的非互反有效和恢复冲程很好地模拟了自然纤毛的跳动。计算了纤毛阻力、微游泳者净位移、速度和效率，并表明该模型可以使用预先指定的磁驱动进行游泳。所提出的方法可用于设计生物医学微型装置，在人体内部的粘性流动中游泳。
We propose a methodology for swimming at low-Reynolds-number flows based on ciliary motion of a microswimmer using magnetic actuation of artificial cilia. By solving the coupled magnetic-elastic-hydrodynamic problem, we demonstrate nonreciprocal effective and recovery strokes for cilia that nicely mimic natural cilia beating. Cilia drag forces, microswimmer net displacement, velocity, and efficiency are calculated, and we show the model can swim using a prespecified magnetic actuation. The proposed methodology can be used for devising biomedical microdevices that swim in viscous flows inside the human body.
