Infiltration through porous media [PDF]
Physical Review E, 2000 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

Transport in Porous Media, 2022 AbstractConnectivity and connectedness are nonadditive geometric functionals on the set of pore scale structures. They determine transport of mass, volume or momentum in porous media, because without connectivity there cannot be transport. Percolativity of porous media is introduced here as a geometric descriptor of connectivity, that can be computed ...

Transport in Porous Media, 2015 Drying of porous media is part of our daily experience, yet this common process is central to many environmental and engineering applications ranging from soil evaporation affecting hydrological water balance and climatic processes, to the drying of food and building materials, and driving plant life through transpiration.

TRANSFERS IN POROUS MEDIA [PDF]
Special Topics & Reviews in Porous Media: An International Journal, 2014 Modelling heat transfer in porous media requires to take into account multiple-scale aspects inherent to porous media structures. Several methodologies have been developed to upscale the equations at a lower-scale and to obtain upper-scale models as it is outlined in a brief review based on a simple heat conduction example proposed in the first part of

Physical Review E, 2004 We address the surface tension-driven dynamics of porous media in nearly saturated pore-space solutions. We linearize this dynamics in the reaction-limited regime near its fixed points -- surfaces of constant mean curvature (CMC surfaces). We prove that the only stable interface for this dynamics is the plane, and estimate the time scale for a CMC ...

Research on Stress Sensitivity of Fractured Carbonate Reservoirs Based on CT Technology
Energies, 2017 Fracture aperture change under stress has long been considered as one of primary causes of stress sensitivity of fractured gas reservoirs. However, little is known about the evolution of the morphology of fracture apertures on flow property in loading ...

Direct Visualization of Nanoscale Salt Precipitation and Dissolution Dynamics during CO2 Injection
Energies, 2022 CO2 injection to enhance shale oil recovery provides a win-win solution to meet the global fuel shortage and realize ultimate carbon neutrality. When shale reservoirs contain high salinity water, CO2 injection can result in salt precipitation to block ...

Effect of surface modification on single-walled carbon nanotube retention and transport in saturated and unsaturated porous media [PDF]
, 2012 This work investigated the effect of different surface modification methods, including oxidization, surfactant coating, and humic acid coating, on single-walled carbon nanotube (SWNT) stability and their mobility in granular porous media under various ...

A Pore-Scale Investigation of Residual Oil Distributions and Enhanced Oil Recovery Methods
Energies, 2019 Water flooding is an economic method commonly used in secondary recovery, but a large quantity of crude oil is still trapped in reservoirs after water flooding.
