Random walk (RW) methods are recurring Monte Carlo methods used to model convective
and diffusive transport in complex heterogeneous media. Many applications can be found …

We study and explain the origin of early breakthrough and long tailing plume behavior by
simulating solute transport through 3‐DX‐ray images of six different carbonate rock …

A major part of the world's remaining oil reserves is in fractured carbonate reservoirs, which
are dual-porosity (fracture-matrix) or multiporosity (fracture/vug/matrix) in nature. Fractured …

We investigate large‐scale particle motion and solute breakthrough in sparse three‐
dimensional discrete fracture networks characterized by power law distributed fracture …

Power law tailing is often observed in the breakthrough curves (BTCs) of tracer tests. Tailing
is attributed to heterogeneity of aquifer properties and cannot be properly modeled by …

We study the interplay of pore-scale mixing and network-scale advection through
heterogeneous porous media, and its role for the evolution and asymptotic behavior of …

Reinjection of CO 2 into producing natural gas reservoirs is considered as a promising
technology to improve gas recovery, mitigate atmospheric emissions and control climate …

The solute transport regime is highly dependent upon the heterogeneity of the flow field. In
this study, the influence of eddies on conservative solute transport through a two …

An efficient and accurate numerical model for multicomponent compressible single-phase
flow in fractured media is presented. The discrete-fracture approach is used to model the …

Mobile‐immobile mass transfer is widely used to model non‐Fickian dispersion in porous
media. Nevertheless, the memory function, implemented in the sink/source term of the …
