Erythrocyte Rheology in a Symmetrically Constricted Microchannel

Article Preview

Abstract:

This paper presents a fluid-cell interaction algorithm using the immersed boundary coupled fictitious domain method. We discuss the application of this method to the numerical investigation of motion and deformation of erythrocytes in two-dimensional stenotic microvessels. The erythrocytes are modeled as biconcave-shaped closed membranes filled with cytoplasm. Simulation results of multiple erythrocytes traversing the stenosis in Poiseuille flow are presented. This algorithm is applicable to a large class of problems involving fluid flow with complex geometry and fluid-cell interactions.
