Preferential Flow Phenomena in Partially-Saturated Porous Media

Preferential flow in unsaturated porous media, in the form of fingers and channels, has been observed to take place in different types of media and at different scales. The preferential flow is caused by fluid instabilities, created by density or viscosity differences, or because of heterogeneities in the geological media. In this study, two very different types of preferential flow problems ar...

Infiltration through porous media.

We study the kinetics of infiltration in which contaminant particles, which are suspended in a flowing carrier fluid, penetrate a porous medium. The progress of the "invader" particles is impeded by their trapping on active "defender" sites which are on the surfaces of the medium. As the defenders are used up, the invader penetrates further and ultimately breaks through. We study this process i...

Infiltration of Initially Dry, Deformable Porous Media

The present paper studies the in ltration of an incompressible liquid in an initially dry (or partially dry), deformable spongeous material made of an incompressible constituent in the slugow approximation having in mind the application to some industrial processes involving ow through spongeous materials and, in particular, some composite materials manufacturing processes. The resulting initia...

Biofilm development and the dynamics of preferential flow paths in porous media.

A two-dimensional pore-scale numerical model was developed to evaluate the dynamics of preferential flow paths in porous media caused by bioclogging. The liquid flow and solute transport through the pore network were coupled with a biofilm model including biomass attachment, growth, decay, lysis, and detachment. Blocking of all but one flow path was obtained under constant liquid inlet flow rat...

Invasion patterns during two-phase flow in deformable porous media

We study the formation of viscous fingering and fracturing patterns that occur when air at constant overpressure invades a circular Hele-Shaw cell containing a liquid-saturated deformable porous medium—i.e., during the flow of two non-miscible fluids in a confined granular medium at high enough rate to deform it. The resulting patterns are characterized in terms of growth rate, average finger t...
