论文摘要
我们介绍了一项实验研究，对在准二维Poiseuille流动中流动的可变形颗粒的狭窄悬浮液的结构进行了实验研究。得益于精确的微流体粘丝体技术与浓度谱的测量相结合，我们的研究提供了结构效应和流变学之间牢固关系的首个实验确认{具有三维粒子}，以前仅在纯二维系统的数值模拟中报道。在由于限制引起的强大结构效应的条件下，有效粘度与颗粒浓度（此处，红细胞）的演变表明，快速生长和高原范围与悬架结构中的定性过渡相关。
We present an experimental study of the rheology and structure of a confined suspension of deformable particles flowing in a quasi-two-dimensional Poiseuille flow. Thanks to a precise microfluidic viscosimetry technique combined with measurements of concentration profiles, our study provides the first experimental confirmation {with three-dimensional particles} of a strong relationship between structuring effects and rheology, previously only reported in numerical simulations of purely two-dimensional systems. In conditions where strong structuring effects take place due to confinement, the evolution of the effective viscosity with particle concentration (here, red blood cells) shows a remarkable succession of ranges of rapid growth and plateaus that are associated to qualitative transitions in the structure of the suspension.
