From Interface Dynamics to Darcy Scale Description of Multiphase Flow in Porous Media
Steffen Berg, Ryan T. Armstrong, Maja Rücker +3
An outstanding characteristic of porous media, desired in many applications, is the large surface area, which facilitates solid-fluid interactions, making porous media an extreme c…

Fluctuation-dissipation theorems for multi-phase flow with memory in porous media
Dick Bedeaux, Signe Kjelstrup, Steffen Berg +2
Recent works have reported on the collective behavior of multiphase systems under fractional flow. Such behavior has been linked to pressure and/or flux fluctuations under stationa…

Fluctuation-dissipation theorems and the measurement of the Onsager coefficients for two-phase flow in porous media
Marcel Moura, Dick Bedeaux, Ryan T. Armstrong +1
We propose a new methodology for the experimental measurement of the Onsager coefficients of porous media flows by application of the fluctuation-dissipation theorem. The experimen…
