标题： Dynamics of fibers in a wide microchannel

摘要： 单个柔性非布朗纤维在两个平行固体平面壁之间的泊肃叶流中的动力学行为，使用基于斯托克斯方程多重展开的流体多重子数值代码进行研究，并对润滑效应进行了修正。 结果显示，在广泛的系统参数范围内，靠近壁面、更柔韧（刚度更低）或更长的纤维向通道中平面迁移的速度会增加。 向通道中心更快的运动伴随着沿流动方向更慢的平移和更大的纤维变形。 显示英文摘要

摘要： Dynamics of single flexible non-Brownian fibers, tumbling in a Poiseuille flow between two parallel solid plane walls, is studied with the use of the hydromultipole numerical code, based on the multipole expansion of the Stokes equations, corrected for lubrication. It is shown that for a wide range of the system parameters, the migration rate towards the middle plane of the channel increases for fibers, which are closer to a wall, or are more flexible (less stiff), or are longer. The faster motion towards the channel center is accompanied by a slower translation along the flow and a larger fiber deformation.
