Abstract

The article considers a mathematical model of blood motion in microvessels of diameter from 4 to 8 μm. The blood is considered as a fluid consisting of plasma and red blood cells (RBCs) fractions, wherein the RBCs fraction has much higher viscosity in contrast with the plasma fraction. As a numerical approach, the finite element method based on the Stokes equations with variable viscosity is applied. The adequacy of the model is assessed by comparing the numerical results and experimental (in vitro and in vivo) data. Different approaches to the construction of suitable boundary conditions are discussed and implemented.
