The effect of drainage front morphology on gaseous diffusion through partially saturated porous media is analyzed using the lattice Boltzmann method (LBM). Flow regimes for immiscible displacement in porous media have been characterized as stable displacement, capillary fingering, and viscous fingering. The dominance of a flow regime is associated with the relative magnitudes of gravity, viscou...

In the context of seismoelectric and self-potential surveying, effective excess charge density electrokinetic coupling coefficient are key parameters relating measured electrical potential hydraulic characteristics explored porous media. this work, we present a novel flux averaging approach that permits to estimate frequency-dependent in partially saturated For this, conceptualize medium as bun...

Infiltration processes in fractured-porous media remain a crucial, yet not very well understood component of recharge and vulnerability assessment. Under partially-saturated conditions flows fra...
