Falcon 20 bizjet aerodynamic modelling

Overview & Synopsis

This study aims at describing an original numerical process that lead to a highly spatially resolved definition of FA20 wake flow using high fidelity RANS 3D simulation. Several simulations are performed coupled with a mesh adaptation process. The aerodynamics is validated by analysis of circulation, vortex evolutions and dilution. For the most refined mesh, the circulation is conserved with distance behind the aircraft, and the dilution follows the same trend as the one obtained by interpolation of experimental data. A strong interaction is observed between the jet and the tail vortex, which is an original inclusion for this aircraft configuration.
