Abstract:
We study linear Lyapunov stability of a resting state for flows of an incompressible viscoelastic polymeric fluid in an infinite plane channel. As a model we choose rheological Vinogradov- Pokrovsky model well suited for describing flow characteristics of linear polymer melts. We find the spectrum of a mixed problem and prove that the solution of a linearised mixed problem in class of a periodic perturbations with regards to the variables, changing along the channel side, is growing faster than the exponent with linear power with the growth of time.
