Stabilizing fluid–fluid displacements in porous media through wettability alteration
We study experimentally how wettability impacts fluid–fluid displacement patterns in granular media. We inject a low-viscosity fluid (air) into a thin bed of glass beads initially saturated with a more-viscous fluid (a water/glycerol mixture). Chemical treatment of glass surfaces allows us to control the wetting properties of the medium and modify the contact angle θ from 5 deg (drainage) to 12...
متن کاملEffect of Vibrations on Pore Fluid Distribution in Porous Media
Understanding the role of shuttle vibrations in pore fluid distribution is an essential task in the exploration of plant growth in root modules aboard space flights. Results from experimental investigations are reported in this paper on the distribution of immiscible fluid phases in glass beads under vibrations. Hexadecane, a petroleum compound immiscible with and lighter than water, was used i...
متن کاملFluctuations in fluid invasion into disordered media.
Interfaces moving in a disordered medium exhibit stochastic velocity fluctuations obeying universal scaling relations related to the presence or absence of conservation laws. For fluid invasion of porous media, we show that the fluctuations of the velocity are governed by a geometry-dependent length scale arising from fluid conservation. This result is compared to the statistics resulting from ...
متن کاملFluid invasion in porous media: viscous gradient percolation.
We suggest that the dynamics of stable viscous invasion fronts in porous media depends on the volume capacitance of the media. At high volume capacitance, our network simulations provide numerical evidence of a scaling relation between the front width and its velocity. In the low volume capacitance regime, we derive a new effective scaling supported by network simulations and that is in agreeme...
متن کاملPorous media plumes: transient filling box solutions
We examine the transient flow of a negatively buoyant, laminar plume in an emptying filling box filled with porous medium. As the system reaches steady state, the box is partitioned into two uniform layers of different densities. However, the approach towards steady state is characterized by a contaminated layer that is continuously stratified. Whereas the presence of a continuous stratificatio...
