• It is well known that capillary pressure depends to a considerable degree upon venous pressure. Bayliss and Starling pointed out the importance of this reationship in 1894, but few studies have dealt with its quantitative aspects. Krogh et al. found that capillary filtration in the human forearm was influenced greatly by venous pressure, although changes of the latter were quantitatively less...

We examine the dynamics of a miscible displacement in capillary, calculating nonequilibrium capillary pressure moving (and slowly diffusing) meniscus. During displacement, varies with time following stretching and smearing interface. The remains different from zero for long (on diffusion scale), slowing displacement. This is however completely ignored by all theories currently available practic...

In this study, a grain-scale modelling technique has been developed to generate the capillary pressure-saturation curves for swelling granular materials. This model employs only basic granular properties such as particles size distribution, porosity, and the amount of absorbed water for swelling materials. Using this model, both drainage and imbibition curves are directly obtained by pore-scale...

Abstract In enhanced oil recovery, foam can effectively mitigate conformance problems and maintain a stable displacement front, by trapping gas reducing its relative permeability in situ. this study, to understand fractures how it affects behavior, we report experiments 1-m-long glass model fracture with hydraulic aperture of 80 $$\upmu $$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML...
