Pore-scale Mixing and the Evolution of Hydrodynamic Dispersion in Porous Media
Alexandre Puyguiraud, Philippe Gouze, Marco Dentz
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 hydrodynamic d…
Transport under advective trapping
Juan J. Hidalgo, Insa Neuweiler, Marco Dentz
Advective trapping occurs when solute enters low velocity zones in heterogeneous porous media. Classical local modeling approaches combine the impact of slow advection and diffusio…
Probability density function (PDF) models for particle transport in porous media
Matteo Icardi, Marco Dentz
Mathematical models based on probability density functions (PDF) have been extensively used in hydrology and subsurface flow problems, to describe the uncertainty in porous media p…
A Coupled Time Domain Random Walk Approach for Transport in Media Characterized by Broadly-distributed Heterogeneity Length Scales
Tomás Aquino, Marco Dentz
We develop a time domain random walk approach for conservative solute transport in heterogeneous media where medium properties vary over a distribution of length scales. The spatia…
Anomalous dispersion in correlated porous media: A coupled continuous time random walk approach
Alessandro Comolli, Marco Dentz
We study the causes of anomalous dispersion in Darcy-scale porous media characterized by spatially heterogeneous hydraulic properties. Spatial variability in hydraulic conductivity…
Enhanced reaction kinetics and reactive mixing scale dynamics in mixing fronts under shear flow for arbitrary Damköhler numbers
Aditya Bandopadhyay, Tanguy Le Borgne, Yves Méheust +1
Mixing fronts, where fluids of different chemical compositions mix with each other, are typically subjected to velocity gradients, ranging from the pore scale to the catchment scal…
