Proceedings Paper • Open AccessSelf-diffusion of erythrocytes in Couette flow studied by elastic light scattering
A gradient of erythrocytes concentration is known to exist in the cross-section of a blood vessel as well as of a model tube. The cell concentration redistribution in shear flow takes place due to self—diffusion , as it was demonstrated on susperions of inorganic particles1. Similar effects are expected to occur in the sedimented fraction of RBC suspension along the vertical gap of Couette viscosimeter after the iruction of shear stress . In our work the elastic light scattering was used to estimate the efficiency of non—aggregating erythrocytes self—diffusion in Couette flow by analyzing the disappearance of distinct boundary between erythrocyte continuum and saline.
