Abstract:

Equations governing thee flow of viscoelastic fluids are classified according to the symbol of their differential operators. Conditions for a change of type in steady two-dimensional flows are derived for a three-constant Oldroyd model. The authors find a change of type in the vorticity equation when a critical condition involving speeds and stresses is satisfied. They also sketch how change of type can be discussed for more general models.
