CERMICS - Fluid Dynamics Group
Left: flood propagation after Malpasset dam failure;
Right: free surface 3D Navier-Stokes flow over inclined heterogeneities
Research activities concern the design and analysis of numerical
methods to approximate problems in environmental sciences and
computational mechanics. Mathematical issues related to the
modeling of such problems are also relevant. Targetted applications
currently include
- underground radioactive waste storage in the framework of the Groupement MoMaS
- shallow water flows on heterogeneous topographies in the framework of
the ANR Project METHODE
- multiscale modeling of clays in collaboration
with ANDRA
- dynamic crack propagation with cohesive forces in collaboration
with EdF R&D
- uncertainty propagation and quantification in collaboration
with LIMSI and BRGM
