Interaction of exhaust jets and aircraft wake vortices: small-scale dynamics and potential microphysical-chemical transformations

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.
