Abstract
Resonance-like phenomena in axisymmetric Poiseuille flows of viscoelastic fluids are theoretically studied. It is shown that instantaneous flow velocities of an upper convected Maxwell fluid with a spectrum of relaxation times drastically increase at certain frequencies of the oscillating pressure gradient. This effect becomes more pronounced as the tube radius gets smaller. Nonlinear liquids are also considered to show that the most effective mean flow rate enhancement for pulsating flows can be reached at the resonance frequencies.
