초록

A generally V-shaped device (40) that is installed on a surface (48) over which there is a flowing medium (50) whose viscosity causes a boundary layer to form between free-stream medium and the surface. The point (46) of the V-shape generator (40) is oriented facing the down stream direction. Usually a plurality of generators (40) are positioned in a line crosswise to the flow spaced so that the vortices created thereby do not interfere. Flow between the arms (42 and 44) of each generator (40) generates a pair of counterrotating vortices (64 and 68) with...

청구항

Vortex generator means including: a flow control surface over which a medium flows from upstream to downstream; and at least two vortex generators positioned on said flow control surface in a cross-stream array, each of said vortex generators being spaced from any adjacent vortex generator and having first and second sidewalls positioned upstanding from said flow control surface, each of said sidewalls having: a tip portion positioned upstream in said flowing medium; an apex portion positioned downstream in said flowing medium; a sidewall first side surf...
