Abstract:
1. An apparatus for controlling flow comprising: a turret extending outwardly from a surface and into an ambient flow that propagates in a predefined flow direction relative to the surface and the turret; and a plurality of ejector nozzles opening through the surface and positioned aft of the turret relative to the ambient flow in a region that would experience flow separation due to the turret without the ejector nozzles, wherein the plurality of ejector nozzles are configured to introduce a motive flow having a greater velocity than the ambient flow to thereby create a mixing region aft of the turret of reduced pressure relative to an ambient pressure in which a portion of the ambient flow mixes with the motive flow, wherein each ejector nozzle comprises an inner nozzle through which motive gas is introduced and a throat surrounding the inner nozzle through which suction gas is introduced at a different pressure than the motive gas such that the motive gas and the suction gas combine to create the motive flow, and wherein the ejector nozzle including the throat and the inner nozzle extend to the surface and open into the mixing region aft of the turret.
