Abstract
A Zonal Detached-Eddy Simulation of the ow around a 3D nite span wing at stall is investigated. The time-averaged ow is in good agreement with wall pressure and Particule Image Velocimetry measurements. In particular, the massive ow separation on the suction side of the wing and the ow reattachement induced by the tip vortex is correctly captured while classical Reynolds-Averaged Navier-Stokes method fails. A more detailed analysis of the unsteady ow structures highlights the large scale range involved in this complex ow.
