Anisotropic Properties of Blood in a Vessel with Stenosis

Аннотация

Preferential orientation of erythrocytes along the flow lines in the vertical plane was observed in the acceleration zone at the entry to the narrow part of the cell and inside this part when whole blood flow in a canal with stenosis was analyzed. An area where the erythrocyte orientation changed was observed in the deceleration zone; erythrocytes assumed an orientation perpendicular to the flow lines in the vertical plane after they passed through this zone. The flow of erythrocytes at a concentration of 1 vol % was studied under the same hydrodynamic conditions in order to characterize the behavior of individual erythrocytes.
