FIELD: aerodynamics; hydrodynamics.
SUBSTANCE: process of flow separation control at streamlined surface involves mechanical effect on turbulent flow evolving in the separation zone by partitions air blow-off from slot-like orifices in the streamlined surface along the flow, behind the separation line of boundary layer at the spreading line of three-dimensional reverse flow.
EFFECT: improved fluid or gas flow in divergent ducts.
