Stability calculations have been performed for a two-dimensional plane Poiseuille flow for Newtonian and upper-convected Maxwell fluids using a finite element code to solve the full equations of motion. Adding elasticity to the flow as modelled by the upper-convected Maxwell model has been shown to destabilize the flow. Our calculations show that this destabilization also occurs for the two-dimensional saturated disturbances that have been presented by Herbert and Jimenez for Newtonian fluids.
