Abstract

Blood flow in a capillary vessel with the hematocrit about 24% is simulated numerically. The immersed boundary method is used for the fluid-red blood cells interaction. The membrane of the red blood cell is modeled as a hyper-elastic thin shell. The numerical results show that the increase of the shear coefficient results in an increase of the pressure drop in the blood flow in capillary vessels in order to sustain the same flux rate of red blood cells.
