| Abstract: |
| We discuss a two-phase model of Stokes-Stokes type for concentrated non-Brownian
suspensions with yield-stress behaviour. We establish a PDE
formulation in terms of a gradient structure, featuring dissipative coupling terms
between fluid and solid phase as well as different driving forces.
Routes of mathematical analysis in the framework of generalized gradient flows and
extentions of this structure to applications in Geosciences are outlined. |
