Abstract:
In this talk we discuss a coupled viscoelastic Navier-Stokes-Biot system describing the interaction between an incompressible, viscous fluid and a poro-viscoelastic medium. The coupling is realized through Beavers-Joseph-Saffman type interface conditions. We establish the global wellposedness of this system in the strong sense for small initial data and derive in addition a Serrin-type blow-up criterion.
