ANR MFG (2016-2021)

Participant : Julien Salomon.

  • Project acronym: MFG

  • Project title: Mean Field Games

  • Coordinator: Sébastien Boyaval (LHSV/ENPC)

  • Funding: 299 160 euros.

CMean field game theory (MFG) is a new and active field of mathematics, which analyses the dynamics of a very large number of agents. Introduced about ten years ago, MFG models have been used in different fields: economics, finance, social sciences, engineering,... MFG theory is at the intersection of mean field theory, mathematical game theory, optimal control, stochastic analysis, variation calculation, partial differential equations and scientific calculation. Drawing on an internationally recognized French team on the subject, the project seeks to obtain major contributions in 4 main directions: the "medium field" aspect (i.e., how to obtain macroscopic models from microscopic models); the analysis of new MFG systems; their numerical analysis; the development of new applications. In this period of rapid expansion of MFG models, the project seeks to foster French leadership in the field and attract new researchers from related fields.

ANR INFAMIE (2015-2019)

Participant : Boris Haspot.

  • Program: ANR Défi de tous les savoirs (DS10) 2015

  • Project acronym: INFAMIE

  • Project title: INhomogeneous Flows : Asymptotic Models and Interfaces Evolution

  • Coordinator: Raphaël Danchin (Univ. Paris-Est)

  • Funding: 232 960 euros.

Our project aims at a better mathematical understanding of several models for the evolution of inhomogeneous flows. Through three main lines of research (see below), we will pursue a twofold final objective. First, we want to develop the current theory of regular solutions for several equations for the evolution of fluids, proposing a new approach and developing tools that are likely to be efficient in various areas of PDEs. Second, for a few selected concrete systems that describe flows in the earth environment or in astrophysics, we wish to use this general approach to extract as much information as possible concerning the qualitative behavior of the solutions.

ANR SEDIFLO (2015-2019)

Participants : Emmanuel Audusse, Martin Parisot.

  • Program: ANR Défi 1 “Gestion sobre des ressources et adaptation au changement climatique” (JCJC)

  • Project acronym: SEDIFLO

  • Project title: Modelling and simulation of solid transport in rivers

  • Coordinator: Sébastien Boyaval (LHSV/ENPC)

Based on recent theoretical and experimental results, this project is aimed at modelling transport of sediments within rivers. It will rely on innovations from the point of view of rheology as well as advanced mathematical tools (asymptotic model reduction, PDE discretisation).

ANR Hyflo-Eflu (2016-2019)

Participants : Jérémy Ledoux, Martin Parisot, Jacques Sainte-Marie, Julien Salomon.

  • ANR project call: Energies marines renouvelables

  • Project acronym: Hyflo-Eflu

  • Project title: Hydroliennes flottantes et énergie fluviale

  • Coordinator: Julien Salomon

The project is a collaboration between the Inria-team ANGE, specialist of free surface flow and optimisation, and the industrial developers of the turbine, HYDROTUBE ENERGIE. The objective of the project HyFlo-EFlu is to deliver a numerical software able to simulate the dynamic of a floating water turbine in real context. For the academic partner, the main challenge is in the simulation of the floating structure at the scale of the river, and the modelling of the vertical and horisontal axis turbine. For the industrial partner, the objective is the validation of the stability of the structure and the performance in term of energy production.

ANR CHARMS (2016-2020)

Participant : Cindy Guichard.

  • ANR project call: Transformations et inter-conversions énergétiques

  • Project acronym: CHARMS

  • Project title: Modèles de réservoirs quantitatifs pour les systèmes hydrothermaux complexes

  • Coordinator: Simon Lopez (BRGM)

  • Funding: 73k euros for LJLL (in 767k euros for the whole project)

CHARMS ANR project is focused on the mathematical methods and software tools dedicated to the simulation of the physical models issued from geothermal engineering. The final objective is the achievement of a highly parallel code, validated on realistic cases.

CNRS Mocha (2017-2018)

Participant : Martin Parisot.

  • CNRS project call: LEFE

  • Project acronym: MOCHA

  • Project title: Multi-dimensiOnal Coupling in Hydraulics and data Assimilation

  • Coordinator: Martin Parisot

  • Funding: 14k euros

In collaboration with S. Barthélémy, N. Goutal, S. Ricci, M. Hoang Le.

Multi-dimensionnal coupling in river hydrodynamics offers a conveninent solution to properly model complex flow while limiting the computational cost and making the most of pre-exsiting models. The project aims to adapt the lateral interface coupling proposed in [35] to the implicit version and test it on real data for the Garonne River.

Inria Project Lab “Algae in Silico” (2015-2018)

Participants : Marie-Odile Bristeau, Yohan Penel, Jacques Sainte-Marie, Fabien Souillé.

In the aftermath of the ADT In@lgae (2013–2015), we developed a simulation tool for microalgae culture. An Inria Project Lab “Algae in Silico” has started in collaboration with Inria teams BIOCORE and DYLISS. It concerns microalgae culture for biofuel production and the aim is to provide an integrated platform for numerical simulation “from genes to industrial processes”.
