Description The stability of the steady flow of a viscous
liquid through a thick-wall, three-layer, viscoelastic tube
with different rheological parameters for each layer is
studied. It is shown that the system can be in both absolute
and convective unstable states. It is shown that the absolute
instability of the system can be converted into a convective
instability, and in some cases the system can even be
stabilized with an appropriate choice of the rheological
parameters. It is found that an anisotropic tube composed
of layers possessing distinct rheological values can
completely eliminate all absolute instability modes. The
present model can be applied to blood vessels that are
composed of three viscoelastic layers with distinct
rheological properties and to distensible tubes conveying
fluids in different technical devices.
