Abstract A study of transonic buffet on the NASA Common Research Model at flight Reynolds numbers is presented. The ability two different hybrid RANS/LES models as well URANS approach for resolving three-dimensional motion was evaluated by means spectral analysis. Automated Zonal DES and simulations show similar results in terms frequency spanwise propagation cells, whereas Delayed Detached Eddy Simulation indicate a strong interaction between flow separation shock motion. extracted...
In this paper, measurements of the stall a NACA [Formula: see text] airfoil section are presented and compared to simulation with hybrid Reynolds-averaged Navier–Stokes (RANS)/large-eddy (LES) model goal gaining deeper insight into flow physics cell turbulent wake in such conditions. Detailed evolution velocity deficit turbulence within along surface pressure visualization provided comprehensive database for code validation studies. The Laminar Wind Tunnel Institute Aerodynamics Gas Dynamics...

In this work, wake-tail plane interactions are investigated for a tandem wing configuration in buffet conditions using hybrid RANS/LES simulations with the Automated Zonal Detached Eddy Simulation (AZDES) method. The analyzed consists of two untapered and unswept segments, representative wing-tail configuration. shock oscillation on front segment development its turbulent wake characterized, including spectral analysis pressure velocity fluctuations modal flow field applying Proper...
