The influence of finite extensibility on the eigenspectrum of dilute polymeric solutions (original) (raw)

Journal of Non-newtonian Fluid Mechanics, 2005

Abstract

Linear stability of plane Couette flow of dilute polymeric solutions modeled using the FENE-P constitutive equation has been examined. Specifically, the spurious, discrete and continuous spectra are identified as a function of the ratio of the solvent to the total viscosity β, maximum chain length L, disturbance wavenumber α and the Weissenberg number (We). It is observed that reducing L
