使用永磁人工纤毛的磁力固流数值模型，我们表明对称跳动纤毛的异时运动在异时波方向上建立了净压力梯度，从而产生单向流。产生的流动被表征为纤毛间距、异时波长度和无量纲参数的函数，该无量纲参数表征了纤毛中粘性力相对于弹力的相对重要性。 (C) 2012 年美国物理研究所。 [doi:10.1063/1.3676068]
Using a magneto-mechanical solid-fluid numerical model for permanently magnetic artificial cilia, we show that the metachronal motion of symmetrically beating cilia establishes a net pressure gradient in the direction of the metachronal wave, which creates a unidirectional flow. The flow generated is characterised as a function of the cilia spacing, the length of the metachronal wave, and a dimensionless parameter that characterises the relative importance of the viscous forces over the elastic forces in the cilia.
