Jet exhaust from a nozzle in phase with starting on the groundComputation with Launder-Sharma k-epsilon turbulence model. Among the computation codes used at DAFE :.
All of the unsteady aeroelastic computations were performed in Navier-Stokes with the Spalart turbulence model, following the Arbitrary Lagrangian Euler formulation, in parallel computing, with multigrid acceleration and with a Backward Euler temporal integration scheme with LU implicitation....
When the flow regime is turbulent, turbulence is simulated, either by a time average of the Navier-Stokes equations completed by a turbulence model (RANS equations), or by a simulation of the large turbulence scales (LES method)....
