Interphase mass transfer is an important solute transport process in two-phase flow in
porous media. During two-phase flow, hydrodynamically stagnant and flowing zones are …

The kinetic interface-sensitive (KIS) tracer experiment is a newly developed method to
quantify the fluid-fluid interfacial area (FIFA) during drainage processes. The concentration …

By employing kinetic interface sensitive (KIS) tracers, we investigate three different types of
glass‐bead materials and three natural porous media systems to quantitatively characterize …

Solute diffusion in partially saturated porous media is an important fundamental process in
many natural and environmental systems. At low water saturation, the solute transport is …

This study investigates the capillary-associated interfacial area during primary drainage in
unconsolidated porous media for different mean grain diameters, employing pore-scale …

An important aspect in groundwater remediation is to understand changes of multiphase
fluid front morphology and stagnant regions on macro scale. However, the prediction of …

Gas migration in the subsurface, a multiphase flow in a porous-medium system, is a problem
of environmental concern and is also relevant for subsurface gas storage in the context of …

Bayesian model selection objectively ranks competing models by computing Bayesian
Model Evidence (BME) against test data. BME is the likelihood of data to occur under each …

Rough fractures with geometric heterogeneity significantly affect the movement
characteristic of the gas–water flow interface. However, studies on gas–water flow in smooth …

A novel reactive smart tracer method, termed the kinetic interface-sensitive (KIS) tracer test,
has been demonstrated in laboratory column experiments to enable measurement of the …
