Steady-state properties of flow in porous media


Objective: Establish a phase diagram for steady-state two-phase flow. Verify experimentally the equations based on non-equilibrium thermodynamics developed under WP1. Establish an experimental basis for introducing osmotic driving forces as described in WP5.

Description: In steady-state two-phase flow, the systems can either present a rich dynamics of fragmentation, motion and coalescence of single-phase fluid clusters, or have nearly frozen and immobile clusters.
