Numerical study about inertial migration of red blood cell under a Newtonian fluid in a microtube


I present a numerical analysis of the lateral movement and equilibrium radial positions of red blood cells (RBCs) with major diameter of 8 µm under a Newtonian fluid in a circular channel with 50-µm diameter. Each RBC, modelled as a biconcave capsule whose membrane satisfies strain-hardening characteristics, is simulated for different Reynolds number Re and capillary numbers Ca, the latter of which indicate the ratio of fluid viscous force to the membrane elastic force. Through the analysis, we quantify the relationship between the power associated with membrane deformation, stable flow modes, and the equilibrium radial position of RBC centroid.
