abstract = {The effect of the hydrodynamic interaction on the dynamics
of flexible and rod-like polymers in solution is
investigated. The solvent is simulated by the
multi-particle-collision dynamics (MPCD) algorithm, a
mesoscale simulation technique. The dynamics of the solvent
is studied and the self-diffusion coefficient is calculated
as a function of the mean free path of a particle. At small
mean free paths, the hydrodynamic interaction strongly
influences the dynamics of the fluid particles. This solvent
model is then coupled to a molecular dynamics simulation
algorithm. We obtain excellent agreement between Our
simulation results for a flexible polymer and the
predictions of Zimm theory. The study of the translational
diffusion coefficient of rod-like polymers confirms the
predicted chain-length dependence. In addition, we study the
influence of shear on the structural properties of rod-like
polymers. For shear rates exceeding the rotational
relaxation time, the rod-like molecule aligns with the shear
flow, leading to an orientational symmetry breaking
transverse to the flow direction. The comparison of the
obtained shear rate dependencies with theoretical
predictions exhibits significant deviations. The properties
of the orientational tensor and the rotational velocity are
discussed in detail as a function of shear rate.},
