Simulation des écoulements liquide gaz dans les milieux de très faible perméabilité avec réseaux de fractures discrètes
Darcy flows in fractured porous media
Part of the COFFEE team (COmplex Flows for Energy and Environnement), I am currently working on Darcy flows in a low permeability porous medium having a discrete fractured network. This work is supervised by R. Masson and K. Brenner with the collaboration of Laurent Trenty (ANDRA), find below two teasers
computations made on cartesian and triangular meshes (derived from FVCA5 meshes) with different fracture networks. The videos require mp4 compatible codecs to be installed on your system.
