(author)A systematic grid convergence study is conducted for the Detached-Eddy Simulation (DES) of the massively separated flow around a NACA0021 airfoil at high angle of attack. In order to study the convergence characteristics of DES/LES problems, velocity fields using a series of grids must be generated that demonstrate sufficient dynamic similarity...conference paper 2006

Braza, M. (author), El Akoury, R. (author), Martinat, G. (author), Hoarau, Y. (author), Harran, G. (author), Chassaing, P. (author)This paper analyses the performances of adapted URANS and DES turbulence^modelling for high-Reynolds 2D and 3D aerodynamic flows with a pronounced periodic character. The flow configurations is the NACA0012 airfoil in pitch (experimental test-case by Mc Croskey & Mc Alistair, 1976) at Reynolds number 0.98x10^6, as well as the inherently unsteady...conference paper 2006
