Abstract
The aggregation of red blood cells (RBC) is a time-dependent process measured clinically for the assessment of possible pathological changes in diseases. In this paper, a quantitative description of the process is suggested to provide the basis for the quantification of their measurement. In addition, the rheological aspect of RBC aggregation is analyzed with the aim of specifying the effect of the mechanism of RBC aggregation on blood rheological behaviour characterized by shear thinning, thixotropy, and viscoelasticity. Rheological predictions are compared with data for time-dependent blood viscosity changes after a sudden stop and sudden increase of shearing.
