review text: We investigate the flow of dilute polymer solutions in viscometric devices where the polymer concentration is allowed to vary due to the existence of nonzero stress gradients. A spectral collocation method is used in order to solve for the axisymmetric steady-state solution of the full set of the governing equations. Two alternative continuum formulations are considered based on a single- and two-fluid concept, respectively.
