Rezumat:

The existence of internal viscoelastic waves below the elastic instability threshold
in the circular Couette flow of a polymer solution is predicted. We present results of calculations
of the dispersion relation of the waves. These weakly attenuating waves are sustained by a nonuniform
elastic stress distribution and should occur in the region of stable stratification of the
hoop elastic stresses in any viscoelastic fluid flow with curvilinear trajectories.
