The deformed behavior of multiple red blood cells in a straight capillary vessel is simulated based on the continuum mechanics. The membrane of red blood cells is modeled as a thin layer with hyper-elastic properties. The in-plane stress is calculated using Skalak's hyper-elastic model; and neo-Hooken model is adopted for the calculation of bending momentum tensor. The coupling of the deformation of the membrane with the flow of surrounding liquid is modeled with the immersed boundary method. The numerical results show that the initial distribution of the red blood cells, symmetrically or asymmetrically to the central line of the flow, does not affect the velocity distribution in the cross section obviously.
