Immiscible two-phase flow in porous media: Effective rheology in the continuum limit
Subhadeep Roy, Santanu Sinha, Alex Hansen
It is becoming increasingly clear that there is a regime in immiscible two-phase flow in porous media where the flow rate depends of the pressure drop as a power law with exponent…
Flow-Area Relations in Immiscible Two-Phase Flow in Porous Media
Subhadeep Roy, Santanu Sinha, Alex Hansen
We present a theoretical framework for immiscible incompressible two-phase flow in homogeneous porous media that connects the distribution of local fluid velocities to the average…
Pore network modeling of the effects of viscosity ratio and pressure gradient on steady-state incompressible two-phase flow in porous media
Magnus Aa. Gjennestad, Mathias Winkler, Alex Hansen
We perform more than 6000 steady-state simulations with a dynamic pore network model, corresponding to a large span in viscosity ratios and capillary numbers. From these simulation…
A Dynamic Network Simulator for Immiscible Two-Phase Flow in Porous Media
Santanu Sinha, Magnus Aa. Gjennestad, Morten Vassvik +1
We present in detail a set of algorithms to carry out fluid displacements in a dynamic pore-network model of immiscible two-phase flow in porous media. The algorithms are general a…
Effective Rheology of Bi-Viscous Non-Newtonian Fluids in Porous Media
Laurent Talon, Alex Hansen
We model the flow of a bi-viscous non-Newtonian fluid in a porous medium by a square lattice where the links obey a piece-wise linear constitutive equation. We find numerically tha…
Effective rheology of two-phase flow in a capillary fiber bundle model
Subhadeep Roy, Alex Hansen, Santanu Sinha
We investigate the effective rheology of two-phase flow in a bundle of parallel capillary tubes carrying two immiscible fluids under an external pressure drop. The diameter of each…
