Abstract
The invention relates to a surface of a body exposed to circumfluent fluid with elevations protruding from the base surface. In order to design the surface of a body exposed to circumfluent fluid with elevations protruding from the base service with an even more favorable flow, it is provided that when the surface is viewed from the top the elevations are bordered in each case by two boundary lines of which the one boundary line is longer and possesses a greater curvature than the other boundary line so that the cross-section area of an airfoil is produced.
Claims19
A surface of a body exposed to circumfluent fluid flow having a boundary layer which comprises a base surface and a plurality of elevations protruding from said base surface to improve the fluid flow in said boundary layer, each of said elevations, when viewed from above, forming first and second boundary lines for guiding fluid flow in said boundary layer along said base surface, said first boundary line being longer and having a greater curvature than said second boundary line to produce a cross-sectional shape of said elevation in the form of an airfoil.
Elevations for a base surface of a body subjected to a directed fluid flow, said elevations having an airfoil form in a cross-sectional plane substantially parallel to said base surface, said airfoil form being generally aligned with said direct fluid flow and including two side boundaries, a first of said boundaries being longer and having a greater curvature than a second of said boundaries, and said base surface including a plurality of said elevations to improve drag efficiency of said surface.
