TLDR
In this paper, the air-water interfacial area (a0) was estimated using the surfactant adsorption concept in unsaturated porous media, where a column composed of several stainless steel rings was used to carry out saturated/unsaturated experiments in three glass beads media.About:

Influence of Viscous and Capillary Forces on Immiscible Fluid Displacement: Pore-Scale Experimental Study in a Water-Wet Micromodel Demonstrating Viscous and Capillary Fingering
TL;DR: In this article, a series of displacement experiments was conducted to investigate the impacts of viscous and capillary forces on displacement stability and fluid saturation distributions in a homogeneous water-wet pore network micromodel with precisely microfabricated pore structures.

Insights into the Relationships Among Capillary Pressure, Saturation, Interfacial Area and Relative Permeability Using Pore-Network Modeling
TL;DR: In this paper, the authors developed two types of pore-network models: a tube model and a sphere-and-tube model with both pore bodies and pore throats.

TL;DR: In this article, the authors used synchrotron based X-ray microtomography to investigate unsaturated flow through a glass bead column and found that the fluid-fluid interfacial area increasing as saturation decreases, reaching a maximum at saturations ranging from 20 to 35% and then decreasing as the saturation continues to zero.

Tracer tests for the investigation of heterogeneous porous media and stochastic modelling of flow and transport—a review of some recent developments
TL;DR: Tracer tests can be performed at laboratory and field-scales with depth integrated (two-dimensional) or multilevel (threedimensional) set-ups, and under natural or forced hydraulic gradient conditions.

Assessing the potential contributions of additional retention processes to PFAS retardation in the subsurface.
TL;DR: An initial assessment of the relative magnitudes and significance of these retention processes for two PFAS of primary concern showed that adsorption at the air-water interface was a primary source of retention for both PFOA and PFOS, and partitioning to bulk NAPL were shown to be significant sources of retention.

Porous Media: Fluid Transport and Pore Structure
TL;DR: In this paper, the authors examined the relationship between transport properties and pore structure of porous material and presented models of pore structures with a discussion of how such models can be used to predict the transport properties of porous media.
