Abstract

L'aérodynamique étudie le mouvement des corps dans un fluide. Cette science pour l'ingénieur regroupe autour d'une application commune, la locomotion, un ensemble de questions qui s'adressent à recherche fondamentale en mécanique des fluides. L'objectif de cet article est de rappeler ces interrogations fondamentales au cœur desquelles on trouve la dynamique des tourbillons, les instabilités hydrodynamiques et la turbulence.
