Viscoelastic Effect on Hydrodynamic Relaxation in Polymer Solutions
arXiv:cond-mat/0209655 · doi:10.1143/JPSJ.72.209
Abstract
The viscoelastic effect on the hydrodynamic relaxation in semidilute polymer solutions is investigated. From the linearized two-fluid model equations, we predict that the dynamical asymmetry coupling between the velocity fluctuations and the viscoelastic stress influences on the hydrodynamic relaxation process, resulting in a wave-number-dependent shear viscosity.
