Transition from viscous fingers to foam during drainage in heterogeneous porous media
Federico Lanza, Santanu Sinha, Alex Hansen +2
We investigate the behavior of drainage displacements in heterogeneous porous media finding a transition from viscous fingering to foam-like region. A pore network model incorporat…
Effective rheology of immiscible two-phase flow in porous media consisting of random mixtures of grains having two types of wetting properties
Hursanay Fyhn, Santanu Sinha, Alex Hansen
We consider the effective rheology of immiscible two-phase flow in porous media with random mixtures of two types of grains with different wetting properties using a dynamic pore n…
Parameterizations of Immiscible Two-Phase Flow in Porous Media
Håkon Pedersen, Alex Hansen
A fundamental variable characterizing immiscible two-phase flow in porous media is the wetting saturation, which is the ratio between the pore volume filled with wetting fluid and…
Local Statistics of Immiscible and Incompressible Two-Phase Flow in Porous Media
Hursanay Fyhn, Santanu Sinha, Alex Hansen
We consider immiscible and incompressible two-phase flow in porous media under steady-state conditions using a dynamic pore network model. We focus on the fluctuations in a Represe…
Darcy's law of yield stress fluids on a treelike network
Vincenzo Maria Schimmenti, Federico Lanza, Alex Hansen +4
Understanding the flow of yield stress fluids in porous media is a major challenge. In particular, experiments and extensive numerical simulations report a non-linear Darcy law as…
Steady-state two-phase flow of compressible and incompressible fluids in a capillary tube of varying radius
Hyejeong L. Cheon, Hursanay Fyhn, Alex Hansen +2
We study immiscible two-phase flow of a compressible and an incompressible fluid inside a capillary tube of varying radius under steady-state conditions. The incompressible fluid i…
A statistical mechanics for immiscible and incompressible two-phase flow in porous media
Alex Hansen, Eirik G. Flekkøy, Santanu Sinha +1
We construct a statistical mechanics for immiscible and incompressible two-phase flow in porous media under local steady-state conditions based on the Jaynes maximum entropy princi…
