Abstract: An apparatus and method for mitigating the formation of the necklace vortex in junction flows is disclosed. A lifting structure for inducing a positive lift vector and having at least one tip for inducing an outward flow is placed ahead of the windward side of an obstacle at which a necklace vortex would be formed. The structure has a bottom surface and is placed above the boundary floor plane (e.g., a plane from which the obstacle protrudes), by a sufficient distance to allow a flowfield to travel between the bottom surface of the structure and the floor plane. Exemplary applications for the invention include reducing scouring at bridges and bridge-like piers or supports, reducing acoustic signature of submarine operations, protecting architectural structures and reducing wind gusts, mitigating wind hazards for geological structures, and enhancing performance of aircraft.
