The unsteady wake from a blunt trailing-edge has been investigated experimentally. Moth c0SeS of fully turbulent and laminar boundary layer aL separation have been studied. Intensive flow visualization by hydrogen bubble technique, velocity measurements in the near--wake region and pressure measurements along the surface trailing-edge reveal. 'several . new aspects of this class of flow_th; highly organized oscillations occur in the wake region. irrespective of the boundary layer at separation whether it is fully turbulent or laminar. A well defiped meehapism for vortex formation and shedding process has been introduced by the aid of topological concepts. Subsequently, a new technique -is elaborated for attenuation of the coherent vertical structural, by interference of a splitter plate, in the near Wake region. These findings assists the existence of a powerful mechanism or absolute instability in the near-wake region as suggested in previous Investigations.
