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 favourable 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 aerofoil is produced.
L'invention concerne la surface (12) d'un corps (10) autour duquel s'écoule un fluide. La surface (12) comprend des éléments en saillie (14) sur la surface de base. Pour favoriser l'écoulement sur une surface (12) ayant des éléments en saillie (14) sur la surface de base d'un corps autour duquel s'écoule un fluide, les éléments en saillie (14), vus d'en haut de la surface (12), sont entourés de deux lignes de délimitation (18, 20), dont la première (18) est plus longue et a une courbure plus marquée que la deuxième (20), de sorte que la superficie de la section des éléments en saillie (14) a la forme d'une surface portante.
