Dynamique des Fluides (DynFluid)

 

Le Laboratoire DynFluid (équipe d'accueil EA 92) est un laboratoire en cotutelle Arts et Métiers ParisTech / Conservatoire National des Arts et Métiers. Il mène des travaux de recherche en Mécanique des fluides, Aérodynamique et Acoustique, avec des applications dans les secteurs aéronautique, automobile et celui des procédés industriels. Il développe des méthodes numériques originales pour simuler des écoulements (le plus souvent en régime compressible) et des phénomènes aéroacoustiques, ou analyser leurs instabilités et il met en œuvre ces méthodes dans le cadre de programmes de recherche nationaux ou internationaux. Le laboratoire collabore également avec de nombreux partenaires industriels et académiques.
