KW - Red blood cells, moving domain, immersed boundary method.
AB - <p style="text-align: justify;">Computational modeling and simulation are presented on the motion of
red blood cells behind a moving interface in a capillary. The methodology is based on an
immersed boundary method and the skeleton structure of the red blood cell (RBC) membrane
is modeled as a spring network. &nbsp;As by the nature of the problem, the computational domain
is moving with either a designated RBC or an interface in an infinitely long two-dimensional
channel with an undisturbed flow field in front of the computational domain. The tanking-treading
and the inclination angle of a cell in a simple shear flow are briefly discussed for the
validation purpose. We then present and discuss the results of the motion of red blood cells behind a moving
interface in a capillary, which show that the RBCs with higher velocity than the interface speed
form a concentrated slug behind the moving interface.</p>
