Adams, JM and Olmsted, PD (2009) Nonmonotonic models are not necessary to obtain shear banding phenomena in entangled polymer solutions. Physical Review Letters, 102 (6). ISSN 0031-9007
Abstract
Recent experiments on entangled polymer solutions may indicate a constitutive instability, and have led some to question the validity of existing constitutive models. We use a modern constitutive model, the Rolie-Poly model plus a solvent viscosity, and show that (i) this simple class of models captures instability, (ii) shear banding phenomena is observable for weakly stable fluids in flow geometries with sufficiently inhomogeneous total stress, and (iii) transient phenomena exhibit inhomogeneities similar to shear banding, even for weakly stable fluids.
