摘要翻译:
我们描述了在低雷诺数下,一对不可伸展的半柔性细丝在均匀恒定力作用下的沉降过程中水动力相互作用的影响。我们分析了这类聚合物在简单几何形状下的不同状态和形态,这使我们能够突出弹性和水动力应力之间相互作用的特点。与纤维几何形状相关的协同和对称破缺效应产生了特征运动,使它们具有不同于刚性和弹性长丝的特性。

英文摘要:
We describe the effect of hydrodynamic interactions in the sedimentation of a pair of inextensible semiflexible filaments under a uniform constant force at low Reynolds numbers. We have analyzed the different regimes and the morphology of such polymers in simple geometries, which allow us to highlight the peculiarities of the interplay between elastic and hydrodynamic stresses. Cooperative and symmetry breaking effects associated to the geometry of the fibers gives rise to characteristic motion which give them distinct properties from rigid and elastic filaments.
