Mathematical analysis of a one-dimensional model for an aging fluid
We study mathematically a system of partial differential equations arising in
the modelling of an aging fluid, a particular class of non Newtonian fluids. We
prove well-posedness of the equations in appropriate functional spaces and
investigate the longtime behaviour of the solutions
On flows of viscoelastic fluids of oldroyd type with wall slip
We consider the boundary-value problem for the steady isothermal flow of an incompressible viscoelastic liquid of
Oldroyd type in a bounded domain with a Navier type slip boundary condition. We prove that under some restrictions on
the material constants and the data, there exists a strong solution which is locally unique. The proof is based on a fixed
point argument in which the boundary-value problem is decomposed into a transport equation and a Stokes system.http://link.springer.com/journal/21hb201
