Self-organization of red blood cell suspensions under confined 2D flows

Abstract : Dynamic self-organized structures with long-range order have been observed in emulsions and suspensions of particles under confined flows. Here, experiments on red blood cell suspensions in quasi-2D confined flows and numerical simulations were combined to explore long-distance self-organization as a function of the channel width, the red blood cell concentration and the flow rate. They reveal and quantitatively describe the existence of red blood cell long-¬-range alignments and heterogeneous cross-stream concentration profiles characterized by red blood cell-¬-enriched bands parallel to the flow. Numerical simulations show that, in addition to the degree of lateral confinement, the key factor for the structural self-organization of a suspension of particles under a confined flow is the deformability of the constituent particles.
