摘要：
We determine weak and classical solutions for steady Poiseuille flows of a Giesekus fluid with zero and non-zero solvent viscosity. A one-dimensional stability analysis and considerations based upon the molecular description of the model help us to determine the physically meaningful solution among multiple solutions. These solutions should prove useful in investigating some interesting phenomena such as "spurt".
