<p>: Surface, exhibiting reduced flow resistance, of a body over which turbulent flow takes place. The surface of the body is provided with grooves (5), which extend in the flow direction and which are separated from one another by ribs (4) which are constructed to have sharp edges. The surface is composed of a multipLicity of individual elements (3), which have the ribs (4) and grooves (5) on their side facing the flow. The individual elements (3) are disposed relative to one another and/or constructed in such a manner that slits are formed on the side facing the flow between the ribs and grooves. The slits are connected with one another by channels (6) disposed below the surface of the individual elements (3) which faces the flow. (Fig. 2)</p> |
