Laminar flow of two phases through a capillary tube with variable square cross-section
TL;DR: In this paper, the angularity of the channels in a porous medium and the variation in their cross-section can be schematized by a constricted capillary tube of square cross-sections.

Effect of geometry on advancing contact angles in fine capillaries
B. Legait,Pierre Sourieau +1 more
TL;DR: In this paper, the Washburn equation is used to describe the laminar flow of two immiscible newtonian fluids in fine capillaries, and a simple model of surface heterogeneity provides a semiquantitative interpretation of this phenomenon.

Capillary rise between closely spaced plates : effect of Van der Waals forces
B. Legait,P. G. de Gennes +1 more
TL;DR: In this paper, the authors show that the film is thickened due to the second plate, and that R−R eff = 1.5 Z(h) for non-retarded Van der Waals forces.
Gravity drainage in a fissured reservoir with fluids not in equilibrium
TL;DR: In this article, the authors show that the oil recovery by gravity drainage increases if the content of intermediate components in the gas or in the liquid phase increases, and this phenomenon has been confirmed by numerical simulations using compositional models.

Effets de la géométrie des pores et de la mouillabilité sur le déplacement diphasique à contre-courant en capillaire et en milieu poreux

- 01 Jun 1988
TL;DR: In this paper, a modelisation montre les effets de la geometrie du systeme and de l'angle de mouillage sur la dynamique du processus and sur l'origine d'un couplage entre phases fluides, which necessite a nouvelle formulation des lois d'ecoulement en milieu poreux.
