One or more channels whose edges generate streamwise vortices from heights coincidental with a local flow-control surface into the channels are used to maintain attached flow of a fluid medium flowing therepast, even in areas of severe regional adverse pressure gradients. The channels are generally triangular in shape with the apex forwardmost in the flow. The channels work very effectively when nested in series and are most effective when the channels extend to the trailing edge of a flow-control surface.
Means to maintain flow of a flowing medium attached to the exterior of a flow control member having a flow control surface, said means including: a first generally triangularly shaped channel submerged in the flow control surface, said triangularly shaped channel having: an apex portion facing the flow of the flowing medium; an end portion positioned downstream in the flow of flowing medium from said apex portion; a floor surface extending from the flow control surface at said apex portion to said end portion; a first sidewall extending between the flow ...
