Description:
A phase transition model for porous media in consolidation is studied. The
model is able to describe the phenomenon of fluid-segregation during the
consolidation process, i.e., the coexistence of two phases differing from fluid
content inside the porous medium under static load. Considering pure Darcy
dissipation, the dynamics is described by a Cahn-Hilliard-like system of
partial differential equations (PDE). The goal, here, is to study the dynamics
of the formation of stationary fluid-rich bubbles. The evolution of the strain
and fluid density profiles of the porous medium is analyzed in two physical
situation: fluid free to flow through the boundaries of the medium and fluid
flow prevented at one of the two boundaries. Morover, an analytic result on the
position of the interface between the two phases is provided.
