Abstract
Résumé

We introduce an hyperbolic two-fluid two-pressure model to compute unsteady two-phase flows in porous media. The closure laws comply with the entropy inequality, and a unique set of jump conditions holds within each field.

On introduit dans cette Note un modèle d'écoulement bifluide hyperbolique pour simuler les écoulements diphasiques en milieu poreux, en configuration instationnaire. Les lois de fermeture proposées sont consistantes avec l'inégalité d'entropie, et les relations de saut sont uniques champ par champ.
