abstract = {The tumbling dynamics of individual polymers in semidilute
solution is studied by large-scale non-equilibrium mesoscale
hydrodynamic simulations. We find that the tumbling time is
equal to the non-equilibrium relaxation time of the polymer
end-to-end distance along the flow direction and strongly
depends on concentration. In addition, the normalized
tumbling frequency as well as the widths of the alignment
distribution functions for a given concentration-dependent
Weissenberg number exhibit a weak concentration dependence
in the cross-over regime from a dilute to a semidilute
solution. For semidilute solutions a universal behavior is
obtained. This is a consequence of screening of hydrodynamic
interactions at polymer concentrations exceeding the overlap
concentration. Copyright (c) EPLA, 2011},
