Airflow simulation around aircrafts, engines, buildings …

The CFD team (Computational Fluid Dynamics) is the biggest one at CERFACS. It focuses on flow simulation while developing advanced numerical methods applied to planes, rockets, helicopters, car engines, turbines, etc. The CFD team is strongly tied to other teams like GLOBC or PAE that also use CFD to forecast climate changes or the environmental impact of aviation: indeed, behind these themes, the equations that govern fluid flows are to be found first.

Calculate this engine before building it !

The CFD team develops essential tools in numerous applicative fields with a today well-known leitmotiv in the industrial world: let's calculate systems (planes, engines) before building them. This allows to reduce the cost of testing by one order of magnitude.  The CFD team is at the centre of this research along with its shareholders.

CFD is also a field where High Performance Computing is to be found : CFD simulations rely on fine computational grids with billions of points running on million-core supercomputers. Performing reliable and efficient calculations is another main focus for which Cerfacs is recognized as a key partner.

ISAF project : To accelerate the transition to SAFs, SAFRAN and CERFACS have together obtained an allocation of 44 million CPU hours on the LUMI-C super-computer as part of the EuroHPC Regular Access call in November 2022.

CERFACS |  11 March 2023

The objective of the ISAF project is to study the impact of SAFs (Sustainable Aviation Fuels) on engine operation and pollutant emissions, using high-fidelity Large Eddy Simulations (LES). The methodology developed at CERFACS combines Analytically Reduced Chemistry (ARC) with a multi-component evaporation model to capture the effect of fuel. The target configurations range from academic burners (CRSB at CORIA, SSB at DLR Stuttgart), to isolated industrial injection systems (MICADO at ONERA, HERON at CORIA) and complete annular combustor configurations (BEARCAT at SAFRAN, NTNU test bench).Read more


A CERFACS article distinguished in Scilight (https://doi.org/10.1063/10.0017474)

CERFACS |  9 March 2023

The recently published paper in Physics of Plasma: "3D particle-in-cell study of the electron drift instability in a Hall Thruster using unstructured grids," by W. Villafana, B. Cuenot, and O. Vermorel ( attracted the attention of Scilight (), whose goal is to present the most interesting research in the physical sciences published in AIP journals."Read more
