On effectue une revue des propriétés dynamiques des tourbillons qui se forment dans les sillages d'ailes d‘avions. Les notions importantes permettant d'appréhender ces écoulements sur un plan physique sont : les ondes d'inertie, les instabilités hydrodynamiques tridimensionnelles résultant des interactions entre tourbillons, la fusion de tourbillons, l’éclatement tourbillonnaire et la turbulence. Toutes ces notions sont discutées sur la base de résultats théoriques, expérimentaux ou numériques.
This paper is a review on the dynamics of vortices in fluids which get involved in aircraft wakes. Basic notions useful to appraise their dynamics are: inertial waves, 3D instabilities due to vortex interaction, vortex merging, vortex breakdown and turbulence. Each one of these topics is illustrated by means of experimental or numerical results.
