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…
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…
Getting out of a tight spot: Cooperative unclogging of hydrogel particles in disordered porous media
Sanjana Kamath, Laurent Talon, Meera Ramaswamy +2
We use event-driven pore network modeling to study the transport of hydrogel particles through disordered porous media -- a process that underlies diverse applications. By simulati…
Influence of the imposed flow rate boundary condition on the flow of Bingham fluid in porous media
Laurent Talon, Andreas Andersen Hennig, Alex Hansen +1
The flow of yield stress fluids in porous media presents interesting complexity due to the interplay between the non-linear rheology and the heterogeneity of the medium. A remarkab…
Relation Between First Arrival Time and Permeability in Self-Affine Fractures with Areas in Contact
Laurent Talon, Harold Auradou, Alex Hansen
We demonstrate that the first arrival time in dispersive processes in self-affine fractures are governed by the same length scale characterizing the fractures as that which control…
Permeability Estimates of Self-Affine Fracture Faults Based on Generalization of the Bottle Neck Concept
Laurent Talon, Harold Auradou, Alex Hansen
We propose a method for calculating the effective permeability of two-dimensional self-affine permeability fields based on generalizing the one-dimensional concept of a bottleneck.…
