Steady-state properties of flow in porous media


Establish a phase diagram for steady-state two-phase flow. Verify experimentally the equations based on non-equilibrium thermodynamics developed under RT 1. Establish an experimental basis for introducing osmotic driving forces as described in RT 5.

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.
