Numerical Simulation of Contrail Formation Using a Simplified Wing-Injector Configuration
Résumé
Contrail formation is a complex topic, since several physical processes are involved, covering a large range of space and time scales, from the engine exit to the atmospheric global scale. In the near field of the aircraft, contrail formation is mainly dominated by microphysics and mixing processes between the propelling jets and the external flow and more precisely during the jet-vortex interaction. In this paper, we present a new approach to focus on the influence of the wing/nacelle configuration on contrail onset. The originality of this work is to provide a preliminary study in order to take into account a complex aircraft geometry in further jet vortex numerical simulations using the ONERA multiphysics code CEDRE.
