A closer look: high-resolution pore-scale simulations of solute transport and mixing through porous media columns
(2022-01)
Article
Open AccessMixing is pivotal to conservative and reactive transport behaviors in porous media. Methods for investigating mixing processes include mathematical models, laboratory experiments and numerical simulations. The latter have ... -
A KDE-based random walk method for modeling reactive transport with complex kinetics in porous media
(2017-11)
Article
Open AccessIn recent years, a large body of the literature has been devoted to study reactive transport of solutes in porous media based on pure Lagrangian formulations. Such approaches have also been extended to accommodate second-order ... -
Enhanced NAPL removal and mixing with engineered injection and extraction
(2022-04)
Article
Open AccessAquifer remediation with in-situ soil washing techniques and enhanced oil removal typically involves the injection of liquid solutions into the geological formation to displace and mobilize non-aqueous phase liquids (NAPLs). ... -
Enhancing degradation of emerging organic compounds in managed aquifer recharge systems by means of chaotic advection
(Universitat Politècnica de Catalunya, 2017-01-27)
Master thesis
Restricted access - author's decisionWater used in Managed Aquifer Recharge (MAR) systems can contain organic micropollutants, which can contaminate the aquifer. The degradation rates of many of these compounds can be enhanced by cometabolism linked to ... -
Enhancing mixing during groundwater remediation via engineered injection-extraction: the issue of connectivity
(John Wiley & sons, 2023-07)
Article
Open AccessIn the context of in situ groundwater remediation, mixing is vital for a successful outcome. A slow mixing rate between the contaminated groundwater and the injected treatment solution can severely weaken the effective ... -
Lagrangian modeling of reactive transport in heterogeneous porous media
(Universitat Politècnica de Catalunya, 2020-03-13)
Doctoral thesis
Open AccessFluid flow, solute transport, and chemical reactions in porous media are highly relevant for multiple applications and in several fields of knowledge. Aquifers are a typical example of porous media, but many others exist, ... -
Lagrangian modeling of reactive transport in heterogeneous porous media with an automatic locally adaptive particle support volume
(2018-10)
Article
Open AccessThe particle support volume is crucial for simulating reactive transport with Lagrangian methods as it dictates the interaction among particles. Assuming that it is constant in space, the particle support volume can be ... -
Numerical equivalence between SPH and probabilistic mass transfer methods for Lagrangian simulation of dispersion
(Elsevier, 2019-04)
Article
Open AccessSeveral Lagrangian methodologies have been proposed in recent years to simulate advection-dispersion of solutes in fluids as a mass exchange between numerical particles carrying the fluid. In this paper, we unify these ... -
Particle density estimation with grid-projected and boundary-corrected adaptive kernels
(Elsevier, 2019-09)
Article
Open AccessThe reconstruction of smooth density fields from scattered data points is a procedure that has multiple applications in a variety of disciplines, including Lagrangian (particle-based) models of solute transport in fluids. ... -

Random-walk modeling of reactive transport in porous media with a reduced-order chemical basis of conservative components
(2021-04)
Article
Open AccessIn this work we employ a reduced-order basis of conservative chemical components to model reactive transport using a Lagrangian (particle tracking) method. While this practice is well-understood in the Eulerian (grid-based) ... -
Smoothed Particle Hydrodynamics for anisotropic dispersion in heterogeneous porous media
(Elsevier, 2024-01)
Article
Open AccessIn the context of modeling solute transport through heterogeneous porous media, particle methods possess inherent advantages with respect to mesh-based (Eulerian) methods. In Smoothed Particle Hydrodynamics (SPH), particles ... -
Solute transport in bounded porous media characterized by Generalized Sub-Gaussian log-conductivity distributions
(Elsevier, 2021-01)
Article
Open AccessThere are increasing evidences that probability distributions and associated statistical moments of a variety of hydrogeological and soil science variables and their spatial increments display distinctive scale-dependent ...
