FRICTIONAL RESISTANCE REDUCING METHOD, STRUCTURE WITH REDUCED FRICTIONAL RESISTANCE AND METHOD FOR FORMING ELECTRODES FOR REDUCING FRICTIONAL RESISTANCE

摘要

PROBLEM TO BE SOLVED: To provide a frictional resistance reducing method for reducing frictional resistance of an object (structure) such as hull, a structure with reduced frictional resistance and a method for forming electrodes for reducing frictional resistance of which direct actions against turbulent boundary layer, for example, a viscosity bottom layer and a buffer area near a surface of hull, for example, realize a local high void ratio or volume concentration of particles, and restrict turbulent flow.SOLUTION: Electrodes 20 are formed at a surface of an object 11 to reduce frictional resistance caused by fluid X, particles and/or air bubbles generated by electrolysis action under application of electrical power to the electrodes 20 are acted from the surface of the object 11 that is an inner wall surface of a turbulent flow interface layer to reduce frictional resistance at the object 11 caused by fluid X.SELECTED DRAWING: Figure 1
