We investigate the convective instability resulting from the dissolution of carbon dioxide (CO) into water in a heterogeneous Hele-Shaw cell utilizing both experimental and n…
openKARST: A novel open-source flow simulator for karst systems
Jannes Kordilla, Marco Dentz, Juan J. Hidalgo
We introduce the open-source Python-based code openKARST for flow in karst conduit networks. Flow and transport in complex karst systems remain a challenging area of hydrogeologica…
Turbulent Pipe Flow of Thixotropic Fluids
Noman Yousuf, Daniel Lester, Murray Rudman +2
Complex materials with internal microstructure such as suspensions and emulsions exhibit time-dependent rheology characterized by viscoelasticity and thixotropy. In many large-scal…
Is Chaotic Advection Inherent to Heterogeneous Darcy Flow?
Daniel R. Lester, Michael G. Trefry, Guy Metcalfe +1
At all scales, porous materials stir interstitial fluids as they are advected, leading to complex distributions of matter and energy. Of particular interest is whether porous media…
Dispersion and mixing in heterogeneous compressible porous media under transient forcing
Satoshi Tajima, Marco Dentz
Periodic forcing of flow in compressible porous media is an important driver for solute dispersion and mixing in geological and engineered porous media subject for example to tides…
Singular Value Decomposition for Single-Phase Flow and Cluster Identification in Heterogeneous Pore Networks
Ilan Ben-Noah, Juan J. Hidalgo, Marco Dentz
Pore networks play a key role in understanding and quantifying flow and transport processes in complex porous media. Realistic pore-spaces may be characterized by singular regions,…
Efficient pore space characterization based on the curvature of the distance map
Ilan Ben-Noah, Juan J. Hidalgo, Marco Dentz
Media classification and the construction of pore network models from binary images of porous media hinges on accurately characterizing the pore space. We present an efficient meth…
European Aerosol Phenomenology -- 8: Harmonised Source Apportionment of Organic Aerosol using 22 Year-long ACSM/AMS Datasets
Gang Chen, Francesco Canonaco, Anna Tobler +67
Organic aerosol (OA) is a key component to total submicron particulate matter (PM1), and comprehensive knowledge of OA sources across Europe is crucial to mitigate PM1 levels. Euro…
Dispersion of motile bacteria in a porous medium
Marco Dentz, Adama Creppy, Carine Douarche +2
Understanding flow and transport of bacteria in porous media is crucial to technologies such as bioremediation, biomineralization or enhanced oil recovery. While physicochemical ba…
Performance of Refined Isogeometric Analysis in Solving Quadratic Eigenvalue Problems
Ali Hashemian, Daniel Garcia, David Pardo +1
Certain applications that analyze damping effects require the solution of quadratic eigenvalue problems (QEPs). We use refined isogeometric analysis (rIGA) to solve quadratic eigen…
Constructed wetlands operated as bioelectrochemical systems for the removal of organic micropollutants
M. Hartl, M. J. García-Galán, V. Matamoros +5
The removal of organic micropollutants (OMPs) has been investigated in constructed wetlands (CWs) operated as bioelectrochemical systems (BES). The operation of CWs as BES (CW-BES)…
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…
Investigative monitoring of pesticide and nitrogen pollution sources in a complex multi-stressed catchment: the Lower Llobregat River basin case study (Barcelona, Spain)
Cristina Postigo, Antoni Ginebreda, Maria Vittoria Barbieri +12
The management of the anthropogenic water cycle must ensure the preservation of the quality and quantity of water resources and their careful allocation to the different uses. Prot…
Remediation of bentazone contaminated water by Trametes versicolor: characterization, identification of transformation products, and implementation in a trickle-bed reactor under non-sterile conditions
Manuel Garcia-Vara, Kaidi Hu, Cristina Postigo +4
Bentazone, an herbicide widely applied in rice and cereal crops, is widespread in the aquatic environment. This study evaluated the capacity of Trametes versicolor to remove bentaz…
