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…
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…
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…
On the statistical properties of fluid flows with transitional power-law rheology in heterogeneous porous media
Laurent Talon
In this work, we study non-Newtonian fluid flow in heterogeneous porous media. We are interested in fluids presenting a specific change in rheology: Newtonian below a certain shear…
The Fate of Shear-Oscillated Amorphous Solids
Chen Liu, Ezequiel E. Ferrero, Eduardo A. Jagla +3
The behavior of shear-oscillated amorphous materials is studied using a coarse-grained model. Samples are prepared at different degrees of annealing and then subject to athermal an…
Numerical study of Bingham flow in macrosopic two dimensional heterogenous porous media
R. Kostenko, L. Talon
The flow of non-Newtonian fluids is ubiquitous in many applications in the geological and industrial context. We focus here on yield stress fluids (YSF), i.e. a material that requi…
