Dissolution patterns and mixing dynamics in unstable reactive flow
Hidalgo, Juan J.; Dentz, Marco; Cabeza Diaz de Ceiro, Yoar; Carrera Ramírez, Jesús (2015-08-16)
Article
Accés obertWe study the fundamental problem of mixing and chemical reactions under a Rayleigh-Taylor-type hydrodynamic instability in a miscible two-fluid system. The dense fluid mixture, which is generated at the fluid-fluid interface, ... -
Enhanced mixing in heterogeneous Buckley Leverett flow due to temporal fluctuations
Bolster, Diogo; Dentz, Marco; Carrera, J.; Espino Infantes, Manuel (EGU, 2008-04-30)

Multicomponent reactive transport in multicontinuum media
Donado, Leonardo David; Sánchez Vila, Francisco Javier; Dentz, Marco; Carrera Ramírez, Jesús; Bolster, Diogo (2009)
Article
Accés obertMulticomponent reactive transport in aquifers is a highly complex process, owing to a combination of variability in the processes involved and the inherent heterogeneity of nature. To date, the most common approach is to ... -

Scale dependence of the hydraulic properties of a fractured aquifer estimated using transfer functions
Pedretti, Daniele; Russian, Anna; Sánchez Vila, Francisco Javier; Dentz, Marco (2016-07)
Article
Accés obertWe present an investigation of the scale dependence of hydraulic parameters in fractured media based on the concept of transfer functions (TF). TF methods provide an inexpensive way to perform aquifer parameter estimation, ... -
Semianalytical solution for CO2 plume shape and pressure evolution during CO2 injection in deep saline formations
Vilarrasa Riaño, Víctor; Carrera Ramírez, Jesús; Bolster, Diogo; Dentz, Marco (2013-01-16)
Article
Accés restringit per política de l'editorialThe injection of supercritical carbon dioxide (CO2) in deep saline aquifers leads to the formation of a CO2 rich phase plume that tends to float over the resident brine. As pressure builds up, CO2 density will increase ... -
Spatial markov processes for modeling Lagrangian particle dynamics in natural flow fields
Borgne, Le; Dentz, Marco; Bolster, Diogo; Carrera, J. (EGU, 2009-05-31)
Comunicació de congrés
Accés obert -
Spreading due to heterogeneity in two-phase flow
Bolster, Diogo; Dentz, Marco; Carrera, J. (EGU, 2009-05-31)
Altres
Accés obert -
Temporal scaling of groundwater discharge in dual and multicontinuum catchment models
Russian, Anna; Dentz, Marco; Le Borgne, Tanguy; Carrera Ramírez, Jesús; Jiménez Martínez, Joaquín (2013-12-01)
Article
Accés obertThis paper presents a multicontinuum approach to model fractal temporal scaling of catchment response in hydrological systems. The temporal scaling of discharge is quantified in frequency domain by the transfer function ... -
The multi-advective water mixing approach for transport through heterogeneous media
Soler Sagarra, Joaquim; Hakoun, Vivien; Dentz, Marco; Carrera, Jesús (2021-10-12)
Article
Accés obertFinding a numerical method to model solute transport in porous media with high heterogeneity is crucial, especially when chemical reactions are involved. The phase space formulation termed the multi-advective water mixing ... -
Transverse effective dispersion coefficients in a chemically heterogeneous medium with flow fluctuations
Zavala Sánchez, Gabriela V.; Dentz, Marco; Sánchez Vila, Francisco Javier (2006)
Text en actes de congrés
Accés obertWe investigate the effective transport of a sorptive solute through a chemically heterogeneous medium subject to temporal fluctuations of the flow conditions. We focus on linear instantaneous sorption, with a spatially ... -
Use of hydraulic tests to identify the residual CO2 saturation at a geological storage site
Martínez Landa, Lourdes; Roetting, Tobias Stefan; Carrera Ramírez, Jesús; Russian, Anna; Dentz, Marco; Cubillo, Bruno (Elsevier, 2013-11-01)
Article
Accés restringit per política de l'editorialEstimating long term capillary trapping of CO2 in aquifers remains a key challenge for CO2 storage. Zhang etal, (2011) proposed a combination of thermal, tracer, and hydraulic experiments to estimate the amount of CO2 ...
