Anomalous Transport in Fracture Networks under Shear-Thinning Flow

Seminar given at IDAEA-CSIC, Barcelona. Shear-thinning fluids are injected into fractured rock by design, in drilling and fracturing operations, in enhanced oil recovery, in remediation and in enhanced geothermal systems. This talk asks whether the rheology changes only how much...

Axisymmetric gravity currents in porous media under the Darcy–Forchheimer regime

We investigate the spreading of axisymmetric Newtonian gravity currents (GCs) propagating within an infinite, saturated porous medium bounded below by a horizontal impermeable surface. The flow is driven by buoyancy, and the intruding fluid advances due to its higher density rela...
