porous media under local steady-state conditions based on the Jaynes maximum entropy …

The co-moving velocity in immiscible two-phase flow in porous media

S Roy, H Pedersen, S Sinha, A Hansen - Transport in Porous Media, 2022 - Springer
We present a continuum (ie, an effective) description of immiscible two-phase flow in porous
media characterized by two fields, the pressure and the saturation. Gradients in these two …

Predicting shear-thinning fluid flows in porous media using pore network modeling: Simulations and experimental validation

A Rodríguez de Castro, M Agnaou, J Gostick - Transport in Porous Media, 2023 - Springer
Pore network modeling (PNM) allows for a major reduction in computational cost when
performing pore-scale flow simulations in porous media. Despite the increasing use of such …

A network model for gas invasion into porous media filled with yield-stress fluid

A Pourzahedi, IA Frigaard - Journal of Non-Newtonian Fluid Mechanics, 2024 - Elsevier
This study investigates the gas invasion into a porous medium filled with a yield-stress fluid.
A pore–throat network model is employed to represent the porous media, and a semi …

Steady-state two-phase flow of compressible and incompressible fluids in a capillary tube of varying radius
