Title:
流れている流体からのエネルギー抽出
Document Type and Number:
Japanese Patent JP4187268
Kind Code:
B2
Abstract:
Method and apparatus for converting the kinetic energy of a moving fluid stream into useful work by using a cascade of thin aero or hydro foils positioned therein. The foils may be provided with at least two degrees of freedom and adjacent foils move out of phase. The foils are subjected to fluid induced oscillations known as flutter. Barriers (3, 43) may be positioned upstream, above, or at sides of the apparatus for increasing efficiency by increasing the fluid velocity. A system of flywheels (17, 18) are used to increase inertia of the foils and are particularly useful with hydrofoils. A cascade of aero or hydro foils may be mechanically oscillated to transfer energy to a fluid.
