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…
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…
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…
Stokes flow paths separation and recirculation cells in X-junctions of varying angle
Mario Cachile, Laurent Talon, Juan M. Gomba +2
Fluid and solute transfer in X-junctions between straight channels is shown to depend critically on the junction angle in the Stokes flow regime. Experimentally, water and a water-…
