Bienvenue - Laboratoire Jacques-Louis Lions

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

• Industrial partnerships and research contracts (in French)
• CIFRE Fellowships (A CIFRE Fellowship is an agreement signed between a company, a PhD student and an academic research laboratory. The company receives financial aid to hire the PhD student that it entrusts with research work which will be the subject of his or her doctoral thesis.)
• Second year Master’s level internships.

• Innovation
• Technological barrier breakthroughs
• Productivity gains

Here are a few examples :

1°) The LRC Manon

Manon is a joint research structure (LRC) shared between the Laboratoire Jacques-Louis Lions (LJLL) - a joint SU-UPD-CNRS - and the Département de modélisation des systèmes et structures(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 :

• 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 laboratory

For example : FreeFem + +, 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.
