COmplex Flows For Energy and Environment

Team presentation

The project aims at studying mathematical models issued from environmental and energy management questions. We consider systems of PDEs of hydrodynamic type or hybrid fluid/kinetic systems.The problems we have in mind involve unusual coupling, which in turn leads to challenging difficulties for mathematical analysis and the need of original numerical solutions. By nature many different scales arise in the problems, which allows to seek hierarchies of reduced models based on asymptotic arguments. The topics require a deep understanding of the modeling issues and, as far as possible boosted by the mathematical analysis of the equations and the identification of key structure properties, we wish to propose innovative and performing numerical schemes.

Research themes

The COFFEE team is particularly interested in the modeling and simulation of * Particulate flows, Mixture flows * Low Mach flows, radiative transfer * Flows in porous media * Simulation of multiphase compositional flows * Plasma physics * Biological degradation (biological damage on monuments, biofilms formation and algae proliferation). It also covers modeling, simulation and analysis of * hyperbolic systems* kinetic equations *, possibly including stochastic effects.

International and industrial relations

The project has established collaborations with several institutes and companies, like ANDRA, BRGM, CEA, Total, GdF-Suez...
