Inertial migration of red blood cells under a Newtonian fluid in a circular channel

We present a numerical analysis of the lateral movement and equilibrium radial positions red blood cells (RBCs) with major diameter 8 $\mathrm {\mu }$ m under Newtonian fluid in circular channel 50 diameter. Each RBC, modelled as biconcave capsule whose membrane satisfies strain-hardening characteristics, is simulated for different Reynolds numbers $Re$ capillary $Ca$ , latter which indicates ratio viscous force to elastic force. The effects initial orientation angles on position an RBC centroid are also investigated. results show that depending their orientations, RBCs have bistable flow modes, so-called rolling tumbling motions. Most motion. These stable modes accompanied by positions, where further away from axis than ones. inertial migration achieved alternating angles, affected primarily angles. Then assume aforementioned during migration, followed at much longer time periods. power (or energy dissipation) associated deformations introduced quantify state loads. expenditures rely centroids, viscosity between internal external fluids.
