abstract = {The flow behavior of a semiflexible polymer in
microchannels is studied using multiparticle collision
dynamics, a particle-based hydrodynamic simulation
technique. Conformations, distributions, and radial
cross-streamline migration are investigated for various
bending rigidities, with persistence lengths L(p) in the
range 0.5 ≤ L(p)/L(r) ≤ 30. The flow behavior is
governed by the competition between a hydrodynamic lift
force and steric repulsion from the wall, which lead to
migration away from the wall, and a locally varying flow
induced orientation, which drives the polymer away from the
channel center and towards the wall. The different
dependences of these effects on the polymer bending rigidity
and the flow velocity results in a complex dynamical
behavior. However, a generic effect is the appearance of a
maximum in the monomer and the center-of-mass distributions,
which occurs at the channel center for small flow
velocities, but moves off-center at higher velocities.},
