Occlusive flow of red blood cells

When red blood cells (RBCs) move through narrow capillaries in the microcirculation, they deform as they flow. In pathophysiological processes such as sickle cell disease and malaria, RBCs' deformability is altered and their motion is severely restricted. This can lead to vaso-occlusive crises with dramatic consequences. To understand the dynamics close to the threshold of occlusion, we used experiments and theory to study the motion of a single swollen RBC through a narrow glass capillary of varying inner diameter. We tracked the motion of the squeezed cell as a function of the driving pressure head and of the confinement diameter, and used a simple elasto-hydrodynamic model to explain the increase in the effective viscosity associated with the occlusion regime.

Information for the speakers

The audience is composed of people with rather heterogeneous backgrounds including specialists in solids, fluids, granular flows, statistical physics... so the idea is to keep your talk understandable by people not necessarily working in your field... The seminar time slot runs from 11am to noon so the best is to make the talk last around 45 minutes to leave some time for discussion.
