The DynFluid laboratory (host team EA 92) is a joint laboratory of Arts et Métiers / Conservatoire National des Arts et Métiers (Cnam).

Organisation

Director: Jean-Christophe ROBINET

The laboratory is organised into 3 research themes and one cross-cutting theme:

Compressible Flow Regimes (ERC) Responsible : X. Gloerfelt	Machine Learning & Uncertainty Quantification (MLQ) Responsible : X. Merle	Instabilities, Transition & Control (ITC) Responsible : D. Biau
High-Performance Computing & Numerical Methods (CMN) Responsible : J.C. Junqueira

DynFluid conducts research in fluid mechanics, aerodynamics and acoustics, with applications in the aeronautics, automotive and industrial process sectors.
It develops original numerical methods to simulate flows (mostly compressible) and acoustic phenomena, or to analyse their instabilities, and applies these methods within national and international research programmes. The laboratory's work helps to:

• Improve the performance of aircraft, rockets, ground vehicles and industrial facilities
• Protect the environment by reducing energy consumption and noise pollution.

In aeronautics and space, the laboratory works in particular with ONERA, CNES, CERFACS, Airbus, Airbus Helicopters, ArianeGroup, Dassault Aviation, MBDA and Safran. In the automotive sector, it has carried out projects for Renault and Stellantis (formerly PSA). In energy and processes, it collaborates with CEA, EDF, Air Liquide and Saint-Gobain, as well as with renewable-energy SMEs such as Enertime and Enogia.

Internationally, DynFluid collaborates in particular with TU Delft, Politecnico di Bari, Sapienza University of Rome, the University of Cambridge, the University of Washington, Ohio State University and JAXA. DynFluid is a host laboratory of the Arts et Métiers doctoral school Sciences des Métiers de l’Ingénieur (SMI, ED 432) and played an active part in setting up the Master's programmes “Fluid Mechanics: Fundamentals and Applications” and “Energy and Environment” (Sorbonne Université / Arts et Métiers).

History

DynFluid was created in June 2009 by merging two former Arts et Métiers laboratories, SINUMEF (Laboratory for Numerical Simulation in Fluid Mechanics) and LEMFI (Laboratory for Energetics and Internal Fluid Mechanics). In 2011, the laboratory joined forces with F. Grasso's Applied Aerodynamics team at Cnam, under a joint supervision agreement between the two institutions.

Directors of the laboratory:
2009 - 2011 Alain LERAT
2011 - 2014 Paola CINNELLA
2014 - 2019 Farid BAKIR
2019 - present Jean-Christophe ROBINET
