Newtonian fluid invasion into a Yield-Stress Fluid-Saturated Medium
Nathan Abitbol, Alex Hansen, Alberto Rosso +2
We investigate pressure imposed two-phase flows in porous media where a Newtonian fluid displaces an immiscible Bingham yield-stress fluid. Using a pore-network model, we identify…
Coordination-number dependent universality in Mixed Wet Percolation
Jnana Ranjan Das, Santanu Sinha, Alex Hansen +1
Mixed-wet percolation was introduced recently in the context of two-phase flow in porous media. In this model, the sites of the primal lattice are occupied with a certain probabili…
Flow of yield stress fluid in a percolating network
Nathan Abitbol, Alex Hansen, Alberto Rosso +1
We study the flow of a Bingham yield-stress fluid in a pore network model where the throats have radii drawn from a uniform distribution. We consider the case in which a fraction o…
Glassy phase transition in immiscible steady-state two-phase flow in porous media
Santanu Sinha, Humberto Carmona, José S. Andrade +1
Two-phase flow in porous media is a ubiquitous phenomenon that has been studied for well over a century. However, we still lack a successful theory that predicts flow on a macrosco…
Immiscible two-phase flow in porous media: a statistical mechanics approach
Alex Hansen, Santanu Sinha
The central problem in the physics of immiscible two-phase flow in porous media is to find a proper description of the flow at scales large enough so that the medium may be regarde…
Pressure drop-flow rate nonlinearity in bubble trains through a capillary bundle
Paolo Botticini, Davide Picchi, Santanu Sinha +1
We investigate the effective rheology of a train of elongated bubbles of negligible viscosity flowing in capillary tubes. Building upon the classical Bretherton theory for a single…
Mixed-wet percolation on a dual square lattice
Jnana Ranjan Das, Santanu Sinha, Alex Hansen +1
We present a percolation model that is inspired by recent works on immiscible two-phase flow in a mixed-wet porous medium made of a mixture of grains with two different wettability…
Geometric structure of parameter space in immiscible two-phase flow in porous media
Håkon Pedersen, Alex Hansen
In a recent paper, a continuum theory of immiscible and incompressible two-phase flow in porous media based on generalized thermodynamic principles was formulated (Transport in Por…
Thermodynamics-Like Formalism for Immiscible and Incompressible Two-Phase Flow in Porous Media
Alex Hansen, Santanu Sinha
It is possible to formulate immiscible and incompressible two-phase flow in porous media in a mathematical framework resembling thermodynamics based on the Jaynes generalization of…
Disorder-induced non-linear growth of viscously-unstable immiscible two-phase flow fingers in porous media
Santanu Sinha, Yves Méheust, Hursanay Fyhn +2
The immiscible displacement of a fluid by another one inside a porous medium produces different types of patterns depending on the capillary number Ca and viscosity ratio M. At hig…
