Title:
摩擦抵抗低減船
Document Type and Number:
Japanese Patent JP4070385
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method of reducing the frictional resistance of a hull, and a frictional resistance reduced ship effectively reducing energy consumption during navigation by reducing frictional resistance with little energy consumption. SOLUTION: In this method of reducing the frictional resistance of the hull 10 by discharging bubbles to the submerged surface 12 of the hull 10, a negative pressure part 41 made low in pressure relative to a gas space with the navigation of the hull 10 is formed in the water to lead gas from the gas space to the negative pressure part 41 in the water while forming water flow 40 locally large in vorticity.
