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.
