  • 1 Buffeting in the air

    The RANS (Reynolds Average Navier Stokes) methods are numerical simulation methods that give results averaged over time; with a very restricted spectrum of excitation frequencies. Conversely, the DES (Detached Eddy Simulation) type methods give unsteady results with a much wider spectrum of frequencies
  • 2 Simulation of the noise of landing gear through CFD*

    In particular, they are averaged over time and are best suited to relatively steady flows. 4 ZDES- Zonal Detached Eddy Simulation
