Mixing and spreading of gravity currents in heterogeneous porous media
Albert Jiménez-Ramos, Juan J. Hidalgo
We analyze the mixing, migration and spreading of a gravity current in a heterogeneous porous medium using high-fidelity numerical simulations. Heterogeneity is represented by log-…
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…
Pore network models to determine flow statistics and structural controls in variably saturated porous media
Ilan Ben-Noah, Juan J. Hidalgo, Marco Dentz
Conceptualizing a porous media as a network of conductors sets a compromise between the oversimplifying conceptualization of the media as a bundle of capillary tubes and the comput…
Transport under advective trapping
Juan J. Hidalgo, Insa Neuweiler, Marco Dentz
Advective trapping occurs when solute enters low velocity zones in heterogeneous porous media. Classical local modeling approaches combine the impact of slow advection and diffusio…
Competition is the underlying mechanism controlling viscous fingering and wormhole growth
Yoar Cabeza, Juan J. Hidalgo, Jesus Carrera
Viscous fingering and wormhole growth are complex nonlinear unstable phenomena. We view both as the result of competition for water in which the capacity of an instability to grow…
Mixing across fluid interfaces compressed by convective flow in porous media
Juan J. Hidalgo, Marco Dentz
We study the mixing in the presence of convective flow in a porous medium. Convection is characterized by the formation of vortices and stagnation points, where the fluid interface…
Mechanisms of Dispersion in a Porous Medium
Marco Dentz, Matteo Icardi, Juan J. Hidalgo
This paper studies the mechanisms of dispersion in the laminar flow through the pore space of a -dimensional porous medium. We focus on pre-asymptotic transport prior to the asy…
