Energetics and Combustion (E.M2.C), CNRS-UPR 288

ENERGY RESEARCH AT THE HEART OF TWENTY-FIRST CENTURY INDUSTRIAL CHALLENGES

Energy and transportation have become major issues likely to severely disrupt the general organization of society. The scarcity of oil, the rational use of fossil fuels, reducing emissions, developing renewable energies and climate change risks pose many scientific questions. High level academic research on energy and combustion from molecular scales to more macroscopic scales and applied studies, in partnership with leading companies and research centers in the field of transport and energy, allows the EM2C laboratory from CNRS at CentraleSupélec, to contribute significantly to the advancement of knowledge of these difficult issues.

To meet these challenges, the research activities of the laboratory are organized around three axes: combustion, non-equilibrium plasmas, physics transfers and transverse action in Applied Mathematics.

Combustion activities focus on the understanding, control, simulation, improvement and optimization of combustion. The objectives are a better understanding of basic mechanisms and their interactions simultaneously developed through experimentation skills, modeling and high performance numerical simulation. This research is also based on innovations in the field of diagnostics, sensors, actuators, control methods and means of simulation.

Studies for non-equilibrium plasmas include firstly a fundamental part of the electric shocks and chemical kinetics and the diagnosis of non-equilibrium plasmas at atmospheric pressure, and, secondly, a component application in the fields of energy (ignition and stabilization of lean mixtures of fuel, hydrogen production ) , aerodynamics, atmospheric re-entry and the environment (waste gas treatment).

Research conducted in the physical transfers team is around the transfer energy by radiation in gaseous media or transfers in porous media and nanothermic. By combining basic approaches and the development of effective models of heat transfer, this research addresses scientific and technological barriers related to applications as diverse as atmospheric re-entry spacecraft, transfer to a heart of a nuclear reactor or nanomaterials.

Transversal action in applied mathematics relies on the implementation of projects at the interface of disciplines using scientific computing and high performance computing (HPC). It is conducted in close interaction with experimental researchers in the laboratory. These studies provide experimental results that are first considered for the validation of the codes developed in the laboratory. Simulations coupled with experimental results then form a new source of in-depth understanding of the physical phenomena studied.
