The Laboratoire Jacques-Louis Lions contributes to several research collaborations (see a partial list in French) :

  • Innovation
  • Technological barrier breakthroughs
  • Productivity gains


Here are a few examples :

1°) The LRC ManonNouvelle fenêtre

Eau pressuriséeManon is a joint research structure (LRC) shared between the Laboratoire Jacques-Louis LionsNouvelle fenêtre (LJLL) - a joint SU-UPD-CNRS - and the Département de modélisation des systèmes et structuresNouvelle fenêtre(DM2S) of the CEA-Saclay Nuclear Energy Division (DEN).

This new structure allows researchers to extend two recently signed research agreements on model coupling and on two-phase thermohydraulics to other scientific themes, jointly selected by the partners.

Scientific themes of the LRC Manon

 

 

The scientific themes of the LRC are related to the modelling, computer simulation and optimization of the complex systems found in the civil nuclear industry. The collaboration focuses on improving currently used numerical tools and most importantly, on developing new and effective numerical methods that enable a better modeling of the physical phenomena encountered in many practical applications.

 

 

 

Based on the current expertise of both partners, research directions are : Problème de couplage de modèles

  • multiphase flow in fluid mechanics
  • multiscale and multiphysics modeling in nuclear reactors,
  • specific numerical methods for neutronics,
  • numerical methods for high performance computing,
  • the inclusion of randomness in physical models.

These themes are not isolated from each other and one of the objectives of the LRC is to consider their interactions.

2°) Advanced Simulation of Hydrocarbon Transport

3°) REO project (INRIA/UPMC)

4°) Annular jet simulation

5°) Software developed in the laboratoryNouvelle fenêtre

 

For example : FreeFem + +Nouvelle fenêtre, an implementation of a language dedicated to the finite element method that helps to easily solve partial differential equations (PDE).

These are just a few examples of the many research collaborations in which the LJLL takes part (see a more complete list). These are mutually-beneficial projects for both parties : they lead to research on fundamental problems which may underlie technological barriers. Conversely, they offer industrial partners the means of significantly improving their competitiveness through technological breakthroughs. In addition, these partnerships allow them to receive enhanced support to finance these efforts of innovation, advanced engineering or applied research.
