Numerical modeling of red blood cell interaction mechanics

Abstract

In this work, a numerical analysis of the mechanics of the interaction of the red blood cell with the vessel wall was carried out. The deformation process is described using an adhesive dissipative elastic model. The influence of the electrostatic double layer and drag force on erythrocyte is investigated. The discrete element method is used to model erythrocyte dynamics. The focus is on the analysis of the effect of different acting forces on the erythrocyte. The results reflect force, displacement, time dependencies. The results indicate the process of erythrocyte deformation before contact, at certain distance from the interacting vessel surface.
