Sub-boundary-layer-scale ramp-like vortex generators that can be mounted on any surface such as the wing of an airplane, the inlet to a propulsion system, the hull of a ship, or any other surface over which a fluid moves, when the objective is to minimize drag, irreversibility losses, or other performance penalties that can occur for reasons such as boundary layer separation or other undesirable boundary layer properties. The disclosed devices acts to passively induce streamwise vortices in the boundary layer, thereby transferring high-momentum fluid tow...
1. A passive boundary layer control element device for positioning on a surface used to control the flow of a fluid medium from an upstream location to a downstream location relative to said device, said device comprising: a first ramp feature upstanding from the surface, said first ramp feature having an inclined ramp face, said inclined ramp face being substantially triangular in shape defining a base edge and a pair of side edges extending from said base edge to an apex, said base edge being generally flush with the surface and said apex being general...
