Coupling of mass transfer and reactive transport for nonlinear reactions in heterogeneous media
Willmann, Mathias; Carrera Ramírez, Jesús; Sánchez Vila, Francisco Javier; Silva Rojas, Orlando Enrique; Dentz, Marco (2010-07-01)
Article
Open AccessFast chemical reactions are driven by mixing‐induced chemical disequilibrium. Mixing is poorly represented by the advection‐dispersion equation. Instead, effective dynamics models, such as multirate mass transfer (MRMT), ... -
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
Open AccessWe 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)
Conference lecture
Open Access -
Multicomponent reactive transport in multicontinuum media
Donado, Leonardo David; Sánchez Vila, Francisco Javier; Dentz, Marco; Carrera Ramírez, Jesús; Bolster, Diogo (2009)
Article
Open AccessMulticomponent 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
Open AccessWe 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
Restricted access - publisher's policyThe 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)
Conference lecture
Open Access -
Spreading due to heterogeneity in two-phase flow
Bolster, Diogo; Dentz, Marco; Carrera, J. (EGU, 2009-05-31)

Open Access -
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
Open AccessThis 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
Open AccessFinding 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)
Conference report
Open AccessWe 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
Restricted access - publisher's policyEstimating 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 ...
