Coupling Methodology within the Software Platform Alliances

CEA, ANDRA and EDF are jointly developing the software platform ALLIANCES which aim is to produce a tool for the simulation of nuclear waste storage and disposal repository. This type of simulations deals with highly coupled thermo-hydro-mechanical and chemical (T-H-M-C) processes. A key objective of Alliances is to give the capability for coupling algorithms development between existing codes. The aim of this paper is to present coupling methodology use in the context of this software platform.Comment: 7 page

Statu quo sur la méthanation du dioxyde de carbone : une revue de la littérature

This review summarizes the statu quo and the perspectives of chemical methanation. CO2 methanation, including catalyst deactivation, reactors, mechanisms, and thermodynamics are presented. This reaction serves as a test bed for our fundamental understanding of heterogeneous catalysis and is used in various industrial processes, including the removal of oxo-compounds (COx) in the feed gas for the ammonia synthesis, in connection with the gasification of coal, where it can be used to produce methane from synthesis gas, and in relation to Fischer–Tropsch's synthesis. Moreover, CO2 methanation became of interest as a renewable energy storage system based on a “power-to-gas” conversion process by SNG (synthetic natural gas) production integrating water electrolysis and CO2 methanation as a highly effective way to store the energy produced by renewables sources. The effectiveness and efficiency of the “power-to-gas” plants strongly depends on the CO2-methanation process

Modeling/simulation of battery safety applied to aeronautics

International audienceThe need for Li-ion batteries is essential both for the more electric aircraft and for all new forms of all-electric or hybrid-electric propulsion. A common feature of the different aeronautical applications is the important safety need and the absence of catastrophic events linked to the use of such batteries, which are known for their high power density but also for their risk of thermal runaway that can lead to uncontrolled physical phenomena on board. The phenomenon of thermal runaway is globally understood from the physical point of view but very difficult to model because it is a very exothermic phenomenon. We propose in this article to make a complete point on this subject and in particular, to approach the modeling of the safety of the batteries applied to the future aircraft and the phenomena of thermal runaway
