Large Eddy Simulation (LES) is increasingly being used for the design of new combustion systems, particularly decarbonized ones. In the case of premixed combustion, part of the flame wrinkling is not resolved on the LES grid and requires specific models.

Comme le réaffirme le rapport du GIEC "Impacts, Adaptation and Vulnerability" (GIEC, 2022), le captage et le stockage du CO2 (CSC) joueront un rôle clé dans la réduction des émissions nettes totales de carbone et donc dans l’atténuation du changement climatique mondial.

Plastics are used in various domains and their production is constantly increasing, which consequently leads to an increase in plastic wastes. The origin of aged plastics is wide, used additives even wider, with high dilution level, which drastically complicate recycling process.

With the emergence of new numerical schemes based on general meshes, new possibilities arise for meshing complex geological environments and thus tackling new challenges for the energy transition, namely CO2 storage and deep geothermal energy.

This project is part of the European ERC Synergy project Karst ( https://erc-karst.eu/ ), which aims to develop a predictive flow model for an entire karst network. We will simulate water flows, possibly marked with tracers, in networks comprising millions of nodes.

Liquid–liquid extraction is a key process in the chemical industry and holds an important place in the study of chemical processes at IFPEN.

Catalysts are very often made of active phases containing metallic elements (such as platinoids, cobalt, nickel…) considered as strategic or even critical because of the economic strain induced by a growing usage in multiple sectors (industrial chemistry, energy storage, electrolysers, …) Hence, the quest for a circular economy approach brings n

Les combustibles solides de récupération (CSR) sont des déchets solides, non dangereux, préparés en vue d’une valorisation énergétique par combustion, pyrolyse ou gazéification. Leur quantité abondante en fait un gisement d’énergie important et une alternative à l’enfouissement des déchets.

L'évolution du marché des véhicules électriques est indéniable, avec des avancées significatives dans l'extension de l'autonomie et des performances des véhicules. Au cœur de ces avancées se trouve la batterie de traction, en particulier les batteries lithium-ion.

Un simulateur d'écoulement est particulièrement utile pour des études de stockages souterrains du CO2. Il permet en effet de tester différents scénarios en simulant de façon couplée des mécanismes physiques issus de domaines différents (géologie, géochimie, mécanique des fluides et du sol...).

Air traffic is responsible for an increasingly significant share of global CO₂ emissions. The use of Sustainable Aviation Fuels (SAFs) offers a promising path toward reducing the carbon footprint of the aviation sector.

Controlling pollutant emissions is one of today’s most pressing environmental challenges. Greenhouse gases (GHGs) and industrial emissions such as methane (CH₄) and hydrogen (H₂) directly impact air quality, safety, and climate change.
