This paper summarizes recent progress made in the understanding of the interaction between exhaust jets and trailing vortices, in the near field of an aircraft wake. Emphasis is placed on the effects of the jet on the wake vortex dynamics and the effects of the wake on the exhaust dispersion, as well as their potential microphysical and chemical transformations. We discuss in detail results of high-resolution numerical simulations of jet/vortex interaction that include microscale turbulent mixing, gas-phase chemistry and contrail formation.
Ce papier décrit les progrès récents concernant l'étude de l'interaction entre les jets propulsifs et les tourbillons de sillage, dans le champ proche d'un avion de transport. Une attention particulière a été portée sur les effets des jets sur la dynamique des tourbillons de sillage et l'influence des ces derniers à la fois sur la dispersion des émissions aussi bien que sur les transformations microphysiques et chimiques, qui peuvent avoir un impact sur l'environnement. Nous discutons les résultats de simulations numériques basées sur des approches DNS et LES, de la dynamique et du mélange à petite échelle ainsi que les transformations chimiques et la formation des traînées de condensation.
