The unsteady turbulent flow around a three-dimensional finite-span wing at stall is investigated by means of a zonal detached-eddy simulation. The computation captures a nondelayed development of unsteady structures at the beginning of the separation and accurately resolves the energy cascade in the fully turbulent mixing layer over a large frequency range. A comparison with the experimental data shows that the zonal detached-eddy simulation approach clearly improves the prediction of the mean flow, whereas classical Reynolds-averaged Navier-Stokes methods usually fail. A spectral analysis of pressure signals highlights the origin and the characteristics of the various unsteady mechanisms involved in this complex flow.
