Abstract:
A new rheological model describing flows of incompressible viscoelastic polymer fluid is studied. Lyapunov’s linear instability of the Poiseuille flow counterpart for the Navier–Stokes equations in a plane infinite channel is proven.
Key words:incompressible viscoelastic polymer fluid, rheological relationship, Brownian particle, dumbbell, Poiseuille solution, well-posedness of mixed problem, linear instability of solutions.
