论文摘要
粘性流是一种有效的机制，可以利用微观的惯性进行流动控制。虽然已经对刚性特征的流媒体进行了彻底的研究，但是当涉及身体依从性时，如在生物环境中，几乎没有人知道。在这里，我们研究了在浸入的软缸的最小情况下对流媒体的体弹性影响。我们的研究揭示了一个额外的流过程，即使在Stokes流中也可用。为流动操纵的高级形式铺平了道路，我们说明了获得的见解如何转化为圆形圆柱体以外的复杂几何形状。
Viscous streaming is an efficient mechanism to exploit inertia at the microscale for flow control. While streaming from rigid features has been thoroughly investigated, when body compliance is involved, as in biological settings, little is known. Here, we investigate body elasticity effects on streaming in the minimal case of an immersed soft cylinder. Our study reveals an additional streaming process, available even in Stokes flows. Paving the way for advanced forms of flow manipulation, we illustrate how gained insights may translate to complex geometries beyond circular cylinders.
