Method of reducing frictional resistance of a hull, and frictional resistance reducing vessel

摘要

In the present invention, perpendicular flows (Fa) along a running direction of a hull (10) are induced accompanying the operation of a vessel, and vortex structures in the vicinity of a submerged surface (11) of the hull are varied by the perpendicular flows. As a result, energy consumption during operation of the vessel can effectively be conserved by reducing the frictional resistance with a low level of energy consumption.
