Research topic: macro dispersion in heterogeneous porous media
Scientific context
Model description
The flow equations are Darcy and mass conservation. Stochastic
models define a random permeability field, with a strong heterogeneity.
The geometry is fixed.
We use Monte-Carlo simulations to estimate the macro spreading and the
macro dispersion.

Participants
This topic started in the Sage team (participant J. Erhel)
with the post-doc of A. Beaudoin, in 2004-2005, in collaboration with
J-R. de Dreuzy, from Geosciences at Rennes. A. Beaudoin was then hired
assistant professor at University of Le Havre and is now assistant
professor at University of Poitiers.
The research continues in the team Sage (participants J.
Erhel, G.Pichot), in
collaboration with J-R. de Dreuzy and A. Beaudoin.
Grants
This work was supported by Inria in 2004-2006, funding the post-doc
and the secondement.
Then it was funded by the ANR CIS with the project MICAS in
2008-2011.
