Abstract
Formations on the surface of bodies for reducing the drag relative to a medium which the body is located in or close to. The formations comprise a plurality of cavities (1,20,40,60). The surface in which the cavities are formed is closed. The cavity has a disruption edge (5,25,44,66) adjacent to the cavity, with the disruption edge located upstream of the cavity, so as to set the flowing medium most proximal to the surface into turbulence upon passing the disruption edge. The cavity has a maximum depth from the surface of at least approximately 2 mm.
