Cerfacs Enter the world of high performance ...

HPC simulation hydrogen based energy

EU energy 2050 roadmap asking for “zero-net” CO2 emissions by 2050 calls for the decarbonation of energy in all energy production systems, with application in aeronautical propulsion, ground-based gas turbines for power generation, industrial furnaces and many other systems. A direct way to achieve this target is to increase the use of the so-called carbon neutral “e-fuels”, i.e., fuels produced in green-energy plants such as dihydrogen (H2), ammonia (NH3) or methane (from captured CO2 and H2).

Conjugate heat transfer simulations (AVBP/AVTP) of a gas turbine combustor operated with hydrogen

Such an extreme change in fuel supply may result in catastrophic consequences on the stability and performances of the combustion system leading to undesirable phenomena such as thermoacoustic instabilities, blow-off or flashback. On top of that, controlling pollutant emissions, and guaranteeing safety, in particular with the use of non-negligible amounts of H2, are mandatory.

The CFD team of CERFACS simulate all these systems ensuring a high level of experience in all the physics involved in these problems (turbulence, combustion, acoustics, atomization and phase change, heat transfer). CERFACS is the world leader for high performance computing of complex industrial systems under realistic conditions.

This is made possible by a set of in-house softwares:

  • ARCANE allows to analyze and reduce chemical schemes usable in LES of H2 and complex fuel combustion and pollutant predictions (NOx, CO and soot). ARCANE is developed in collaboration with Cornell University (Pr. Pepiot).
  • The LES solver AVBP features stable low dispersive and low dissipative numerical methods, with specific developments for the integration of stiff chemistry and high parallel efficiency, allowing in particular a local time-stepping strategy based on coupled subdomains.
  • Advanced coupling strategies of the AVBP code with thermal solvers AVTP (conduction) and PRISSMA (radiation) are available to address conductive / convective and radiative heat transfer in high-performance conjugate heat transfer simulations.

H2-based and clean energy is a major concern for many CERFACS Shareholders: Airbus, Safran and ONERA for aeronautical propulsion; EDF for production of electricity; Total for petrochemistry and conversion to renewable energy. It is also a major concern in many sectors, in particular ground-based gas turbines (Ansaldo), and all sectors using furnaces as a source of heat for the production of, for example, glass (Saint-Gobain), cements, chemical products, etc.

A bronze medal to Cerfacs for “Allons-Y À Vélo” !

CERFACS |  26 July 2021

A bronze medal to Cerfacs for "Allons-Y À Vélo" ! Cerfacs is on the podium for its cycling regularity during the "Allons-Y À Vélo" period (May 25 - June 25) in its category (100-500 employees).During this period, 37% of Cerfacs employees came to work by bike during at least 4 consecutive days. "Allons-Y À Vélo" is a campaign organised by the association "2 Pieds 2 Roues" and "La Maison du Vélo de Toulouse" to promote the use of the bicycle for every day travels; all details can be found on allonsyavelo.le-pic.org . Cerfacs encourages its employees to use their bicycle to come to work as they benefit from the bicycle mileage allowance (FMD for Forfait Mobilité Durable) of up to 500 Euros per year.Read more


The H2OPE project wins the prize Joseph Fourier 2021

CERFACS |  26 July 2021

The H2OPE project wins the prize Joseph Fourier 2021 The prize, launched by Atos and GENCI, aims to reward the work of researchers, academics and industry in two strategic areas: Advanced Computing (HPC, Quantum, Edge) and Artificial Intelligence, and, in the 2021 edition , gives particular importance to Decarbonation. The 1st Prize was awarded to the H2OPE or “H2OPErability for safe and clean gas turbine engines” project from CERFACS in Toulouse. This project aims, via the LES AVBP code, to model at high resolution a mixed combustion process associating conventional fuels with hydrogen (bi-fuels) as one of the most promising technical solutions to achieve "net zero emissions" of CO2 in the industrial sector. It was presented by Walter Agostinelli, Davide Laera, Laurent Gicquel, and Thierry Poinsot. Press release :Read more
