Dissipative particle dynamics simulations of bead-spring dumbbell models under microchannel flow were
performed and the effects of the deformation on their migration behavior were discussed. Dumbbells were
found to migrate toward the walls or the channel center depending on the stiffness. Stiff dumbbells migrated
toward the walls. In any cases, the dumbbells were found to have a stronger tendency to move toward the
channel center in more deformable conditions.
