| Abstract: | Schneggenburger et al. [C. Schneggenburger, M. Kröger, S. Hess, An extended FENE dumbbell theory for concentration dependent shear-induced anisotropy in dilute polymer solutions, J. Non-Newtonian Fluid Mech. 62 (1996) 235] extended the original FENE dumbbell kinetic theory to describe concentration dependent shear-induced anisotropy in dilute polymer solutions by a mean-field approach. Besides providing an erratum to the above-mentioned paper and two revised figures we present related analytic results for steady shear and uniaxial elongational flow. Within the same framework we further consider a modified FENE potential and briefly discuss its implications. |
