Effects of Wall Roughness on Coupled Flow and Heat Transport in Fractured Media
Alessandro Lenci, Yves Méheust, Maria Klepikova +2
Heat transfer in fractured media is governed by the interplay between advective transport along rough-walled fractures and conductive transport, both within the fractures and in th…
Stochastic Modeling and Upscaling of Hydrodynamic Transport in Geological Fractures
Alessandro Lenci, Yves Méheust, Marco Dentz +1
Characterizing hydrodynamic transport in fractured rocks is essential for carbon storage and geothermal energy production. Multiscale heterogeneities lead to anomalous solute trans…
Numerical analysis of the large deviation regime of a kinetic equation with a nonlocal Hamilton-Jacobi limit
Hélène Hivert, Tino Laidin
We develop and study an asymptotic-preserving (AP) numerical scheme for a linear kinetic equation in a large deviation regime. After applying a Hopf-Cole transform to the distribut…
A Unified Theory for Chaotic Mixing in Porous Media: from Pore Networks to Granular Systems
Daniel Lester, Joris Heyman, Yves Meheust +1
Recent studies have revealed the central role of chaotic stretching and folding at the pore scale in controlling mixing within porous media, whether the solid phase is discrete (as…
On the mechanism of thermal self-regulation of trees: a kind of homeothermic observation
Jean-Baptiste Boulé, Jean de Bremond d'Ars, Vincent Courtillot +6
What is certain is that surface temperatures around the globe vary considerably, regardless of the time scales or underlying causes. Since 1850, we have observed an average increas…
Numerical approximation of a class of constrained Hamilton-Jacobi equations
Benoît Gaudeul, Hélène Hivert
In this paper, we introduce a framework for the discretization of a class of constrained Hamilton-Jacobi equations, a system coupling a Hamilton-Jacobi equation with a Lagrange mul…
