Abstract
Method and assembly for extracting energy from a flowing fluid. It is proposed to regard all devices of the assembly together as one flow body. In particular those devices on the upstream side of the assembly are set such that they exert lateral (horizontal and/or vertical) forces on the fluid flow, as a result of which flows are produced that guide fast fluid through the energy-extracting devices and guide slow fluid precisely away therefrom. The assembly includes a wind farm and the devices that generate the lateral forces are a type of vortex generators for the atmospheric boundary layer; more particularly they are horizontal or vertical wind turbines positioned at an angle to the wind.
Claims29
Method for extracting energy from a flowing fluid, using an assembly of energy extracting devices positioned close to one another, a guiding device of said assembly being set with respect to said fluid flow in such a way that additional flow results having forces with a component perpendicular to the undisturbed direction of flow are exerted, such that a flow with higher kinetic energy or with lower kinetic energy, compared with a situation in which said force component is lacking, is guided through an energy-extracting device of the assembly, said flow being effective for at least energy extracting devices, wherein at least one guiding device is a horizontal shaft turbine, the rotor shaft of which makes an angle of more than 5 degrees with respect to the undisturbed direction of flow.
Assembly comprising a plurality of devices for extracting energy from a fluid flow, said assembly comprising a guiding device by means of which forces having a component perpendicular to the undisturbed direction of flow are generated, such that fluid with kinetic energy differing from the kinetic energy that is effective in the situation where said force component is lacking is fed through said devices for extracting energy from a fluid, wherein said guiding device is a horizontal shaft turbine, the rotor shaft of which makes an angle of more than 5° with respect to the device for extracting energy from a fluid flow.
