    "abstract": "We study the deformation and motion of an erythrocyte in fluid flows via a\nlattice Boltzmann method. To this purpose, the bending rigidity and the elastic\nmodulus of isotropic dilation are introduced and incorporated with the lattice\nBoltzmann simulation, and the membrane-flow interactions on both sides of the\nmembrane are carefully examined. We find that the static biconcave shape of an\nerythrocyte is quite stable and can effectively resist the pathological changes\non their membrane. Further, our simulation results show that in shear flow, the\nerythrocyte will be highly flattened and undergo tank tread-like motion. This\nphenomenon has been observed by experiment very long time ago, but it has\nfeazed the boundary integral and singularity methods up to the present. Because\nof its intrinsically parallel dynamics, this lattice Boltzmann method is\nexpected to find wide applications for both single and multi-vesicles\nsuspension as well as complex open membranes in various fluid flows for a wide\nrange of Reynolds numbers.",
