Interplay of viscosity and wettability controls fluid displacement in porous media
Saideep Pavuluri, Ran Holtzman, Luqman Kazeem +3
Direct numerical simulations are used to elucidate the interplay of wettability and fluid viscosities on immiscible fluid displacements in a heterogeneous porous medium.We classify…
Onset of convective instability in an inclined porous medium
Emmanuel E. Luther, Michael C. Dallaston, Seyed M. Shariatipour +1
The diffusion of a solute from a concentrated source into a horizontal, stationary, fluid-saturated porous medium can lead to a convective motion when a gravitationally unstable de…
Onset of transient convection in a porous medium with an embedded low-permeability layer
Emmanuel E. Luther, Seyed M. Shariatipour, Ran Holtzman +1
Deep saline aquifers used for CO sequestration are commonly made of sedimentary formations consisting of several layers of distinguishable permeability. In this work, the effec…
Immiscible fluid displacement in porous media with spatially correlated particle sizes
Oshri Borgman, Thomas Darwent, Enrico Segre +2
Immiscible fluid displacement in porous media is fundamental for many environmental processes, including infiltration of water in soils, groundwater remediation, enhanced recovery…
Drying and percolation in spatially correlated porous media
Soumyajyoti Biswas, Paolo Fantinel, Oshri Borgman +2
We study how the dynamics of a drying front propagating through a porous medium are affected by small-scale correlations in material properties. For this, we first present drying e…
The Effect of Gravitational Settling on Concentration Profiles and Dispersion Within and Above Fractured Media
Tomer Duman, Ran Holtzman, Uri Shavit
The transport of heavy particles in a medium that consists of fluid and solid phases such as stream gravel beds, cracked soils and wetlands is affected by processes such as attachm…
Reactive transport under stress: Permeability evolution in deformable porous media
Roi Roded, Xavier Paredes, Ran Holtzman
We study reactive transport in a stressed porous media, where dissolution of the solid matrix causes two simultaneous, competing effects: pore enlargement (chemical deformation), a…
Validating pore-scale models of drying using microfluidic experiments
Paolo Fantinel, Oshri Borgman, Ran Holtzman +1
We present an experimental micro-model of drying porous media, based on microfluidic cells made of arrays of pillars on a regular grid, and complement these experiments with a matc…
Impact of spatially correlated pore-scale heterogeneity on drying porous media
Oshri Borgman, Paolo Fantinel, Wieland Lühder +2
We study the effect of spatially-correlated heterogeneity on isothermal drying of porous media. We combine a minimal pore-scale model with microfluidic experiments with the same po…
Wettability stabilizes fluid invasion into porous media via nonlocal, cooperative pore filling
Ran Holtzman, Enrico Segre
We study the impact of the wetting properties on the immiscible displacement of a viscous fluid in disordered porous media. We present a novel pore-scale model that captures wettab…
