A closer look: high-resolution pore-scale simulations of solute transport and mixing through porous media columns
Solé Marí, Guillem; Bolster, Diogo; Fernández García, Daniel (2022-01)
Article
Accés obertMixing 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
Solé Marí, Guillem; Fernández García, Daniel; Rodríguez Escales, Paula-Felicidad; Sánchez Vila, Francisco Javier (2017-11)
Article
Accés obertIn 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
Wang, Yufei; Fernández García, Daniel; Solé Marí, Guillem; Rodríguez Escales, Paula-Felicidad (2022-04)
Article
Accés obertAquifer 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
Solé Marí, Guillem (Universitat Politècnica de Catalunya, 2017-01-27)
Projecte Final de Màster Oficial
Accés restringit per decisió de l'autorWater 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
Bertran Oller, Oriol; Fernández García, Daniel; Solé Marí, Guillem; Rodríguez Escales, Paula-Felicidad (John Wiley & sons, 2023-07)
Article
Accés obertIn 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
Solé Marí, Guillem (Universitat Politècnica de Catalunya, 2020-03-13)
Tesi
Accés obertFluid 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
Solé Marí, Guillem; Fernández García, Daniel (2018-10)
Article
Accés obertThe 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
