✦ Synopsis

A macroscopic description of a two-phase flow in a porous medium is given by writing, firstly, mass and momentum-balance equations and, secondly, phenomenological equations derived from the theory of irreversible thermodynamic processes. The main results are as follows: (i) the law of capillary pressure is extended to dynamic conditions, (ii) an extended formulation of Darcy's law is established for each fluid phase and also for fluid/fluid interface which is considered as a phase of the system, and (iii) a coupling may appear between fluid phases.

## Abstract An analysis describing viscoelastic flow of a FENE fluid in packed beds or porous media is presented based on the capillary hybrid model of the flow. A close similarity is revealed between the functional relationship of the reduced elongational viscosity to and that relating the reduced
