Simulated two-dimensional motion and deformation of red blood cells in branching capillaries

Abstract: solated red blood cell movement, deformation, and partitioning in small diverging microvessel bifurcations are simulated using a two-dimensional flexible-particle model. While simulated red blood cell trajectories tend to follow background fluid streamlines, significant deviations from these streamlines can occur because of red blood cell migration towards vessel centerlines and RBC obstruction of downstream vessels. The net effect of these behaviors is explored in symmetric branching capillaries to produce results comparable with experiment.
