Title:
VIBRATION AND DRAG REDUCTION SYSTEM FOR FLUID-SUBMERSED HULLS
Document Type and Number:
WIPO Patent Application WO2000035744
Kind Code:
A8
Abstract:
A system for reducing hydrodynamic drag and vortex-induced-vibration in a bluff hull (400). The bluff hull has an internal area (510) filled with fluid, and pumps (504) pump to nozzles, preferably ones of vertically aligned slots (402). The fluid may be ejected tangentially of the hull, and at a higher velocity than the current so as to reduce flow separation.
