Title:
流体への及び流体からの運動エネルギーの伝達
Document Type and Number:
Japanese Patent JP2008542621
Kind Code:
A
Abstract:
Method and apparatus for converting the kinetic energy of a moving fluid stream into useful work by using a parallel cascade of aerofoils or hydrofoils positioned therein. The foils may be provided with at least two degrees of freedom and adjacent foils move in antiphase. The foils are subjected to resonant oscillations, known as flutter, induced by the fluid flow. Profiled inflow and outflow ducts may be positioned upstream and downstream, and the apparatus may be enclosed in a profiled duct, to increase efficiency by altering the fluid velocity and pressure. The foils are cantilevered, supported by vertical rods but are otherwise unattached. A cascade comprised of independent foil modules, each including a foil, a power conversion module and a motion control module, may be programmed to (1) receive energy from a fluid stream to generate power, or (2) transfer energy into a fluid stream to create propulsion or pumping.
