It is disclosed a method for reducing the viscous friction due to the relative movement of a fluid and an object, wherein the object has an external surface in contact with a layer of the fluid and wherein the external surface has a base plane. The method comprises the following steps: forming on the external surface a plurality of projections projecting from the base plane; and imparting to the layer of fluid, by means of the plurality of projections, a profile with a periodic trajectory parallel to the base plane.

Abstract
It is disclosed a method for reducing the viscous friction due to the relative movement of a fluid and an object, wherein the object has an external surface in contact with a layer of the fluid and wherein the external surface has a base plane.
