Non-Newtonian rheology in a capillary tube with varying radius
Federico Lanza, Alex Hansen, Alberto Rosso +1
The flow through a capillary tube with non-constant radius and where bubbles of yield stress fluid are injected is strongly non-linear. In particular below a finite yield pressure…
Role of pore-size distribution on effective rheology of two-phase flow in porous media
Subhadeep Roy, Santanu Sinha, Alex Hansen
The flow of immiscible fluids inside a porous medium shows non-linearity in the form of a power law in the rheological properties of the fluids under steady state flow conditions.…
Rheology of immiscible two-phase flow in mixed wet porous media: Dynamic pore network model and capillary fiber bundle model results
Hursanay Fyhn, Santanu Sinha, Subhadeep Roy +1
Immiscible two-phase flow in porous media with mixed wet conditions was examined using a capillary fiber bundle model, which is analytically solvable, and a dynamic pore network mo…
Onsager-Symmetry Obeyed in Athermal Mesoscopic Systems: Two-Phase Flow in Porous Media
Mathias Winkler, Magnus Aa. Gjennestad, Dick Bedeaux +3
We compute the fluid flow time-correlation functions of incompressible, immiscible two-phase flow in porous media using a 2D network model. Given a properly chosen representative e…
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…
