Article
Modeling heat transfer in complex heterogeneous fractured system is key for geothermal energy applications. Discrete fracture network (DFN) modeling is the classical framework to reproduce the advective part of the transport, which is determined by the fracture connectivity and heterogeneity. This approach in general sacrifices the representation o...
Conference Paper
The United States and countries around the world face an increasing demand for energy at the same time that carbon emissions and other environmental issues are facing greater scrutiny. Geothermal energy, generating electricity using the temperature difference between the surface and the sub-surface, is an active topic of research by the US Departme...

Modeling heat transfer in complex heterogeneous fractured system is key for geothermal energy applications. Discrete fracture network (DFN) modeling is the ideal framework to reproduce the advective part of the transport, which is determined by the fracture connectivity and heterogeneity. This approach in general sacrifices the representation of th...
Article
We aim to test the performances of an incompressible turbulence Reynolds-Averaged Navier–Stokes one-closure equation model in a boundary layer (NSTKE model). We model a new boundary condition for the turbulent kinetic energy k (TKE), and we achieve the mathematical analysis of the resulting NSTKE model. A series of direct numerical simulation are p...

DFN.lab is a modular computational suite to deal with three-dimensional discrete fracture networks (DFN) models from DFN generation to simulation and analysis of connectivity, flow, mechanical and transport properties. DFN.lab is developed by the Fractory, a joint laboratory between the French institute for scientific research (CNRS), the universit...

There is no satisfactory model to explain the mean velocity profile of the whole turbulent layer in canonical wall-bounded flows. In this paper, a mean velocity profile expression is proposed for wall-bounded turbulent flows based on a recently proposed stochastic representation of fluid flows dynamics. This original approach, called modeling under...
Thesis
Le modèle RANS à une équation de fermeture est utilisée avec une nouvelle longueur de mélange. par interpolation, notre loi est universelle. Nous avons étendue ce résultat pour considérer les fonds rugueux. L'existence d'une solution au système d'équation associée est montrée, c'est un problème elliptique avec un terme source dans L¹. Nous utilison...

To date no satisfying model exists to explain the mean velocity profile within the whole turbulent layer of canonical wall bounded flows. We propose a modification of the velocity profile expression that ensues from a recently proposed stochastic representation of fluid flows dynamics. This modeling, called modeling under location uncertainty intro...
Chapter
We recall what are the different known solutions for the incompressible Navier-Stokes Equations, in order to fix a suitable functional setting for the probabilistic frame that we use to derive turbulence models, in particular to define the mean velocity and pressure fields, the Reynolds stress and eddy viscosities. Homogeneity and isotropy are disc...
