A New Coupled Method for Viscoelastic Flow Simulation

Abstract

A new coupled method for finite element viscoelastic flow simulation is presented. Although the method is not free of instabilities, it allows high Weissenberg number flows to be modeled with a simpler mixed element than that of Marchal and Crochet. Numerical results for the planar four-toone contraction are included that illustrate the good performance of our scheme.
