A MATHEMATICAL MODEL OF ERYTHROCYTE SEDIMENTATION IN CAPILLARIES I. V. Yamaikina and E'. V. Ivashkevich UDC 532.529+577 A mathematical model of the process of erythrocyte sedimentation is developed that contains only two optimization parameters, namely, a rheological parameter and the hydrodynamic-resistance radius of a cell. It satisfactorily describes experimental data and can be used to judge the deformability of erythrocytes from their kinetic data and to determine the viscosity of suspensions without a viscosimeter.
