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…
