Abstract [en]

The instability characteristics of a turbulent flat plate boundary layer separating under a strong adverse pressure gradient are examined. The analysis is based on the data of direct numerical simulation. A theoretical model of harmonic perturbations is considered, including the contribution of the turbulent part of the flow, to investigate the stability characteristics of the flow. The structure of the organized waves is also investigated by means of Proper Orthogonal Decompositions (POD).
