  • the wind turbines upstream guide the total flow can be influenced by the flow channel, which can form an unobstructed channel flow in the running in the direction of the channel wall starting position of the opposing baffles.
  • the free flow cross-section is increasingly reduced with the effect that adjusts an increasingly accelerating against the wind turbines channel flow.
  • the flow velocity of the wind turbines can thus be kept substantially constant, which has a favorable effect on the efficiency of the wind power plant.
  • mutually pivotable baffles can also lock the flow channel, so that assembly and maintenance can be performed without wind hazard within the flow channel.
  • the assignment of mutually independently adjustable baffles to the individual wind turbines also creates the opportunity to subdivide the flow channel between the individual wind turbines associated baffles height by at least one partition. This subdivision creates an advantageous prerequisite for blocking the flow channel only in the region of or in the region of a group of wind turbines, depending on the arrangement of individual partitions.
  • the partial flows to the individual wind turbines can be better guided by such a division of the flow channel into sub-channels.
  • baffles have at least two mutually articulated sections parallel to the pivot axis of the baffles, which are mutually pivotally adjustable.
  • hingedly connected Leitwandabitese namely nozzle ratios can be adjusted, which allow an improved laminar flow of the wind turbines due to a decreasing with respect to the channel flow slope of successive in the flow direction Leitwandabitese.
  • Flow channels between each two structures are aligned with respect to a given main wind direction, which often rotates 180 degrees in a day-night rhythm. It is recommended in such a case, in opposite directions to use inflatable wind turbines and to provide the flow channel on both sides of the wind turbines, each with an additional guide in order to use the thus given control interventions in both directions.

  • the baffles 12 on the Anström direction 18 facing away from the wind turbines 3 are in their initial position, which extends substantially along the channel wall 8 in order to create in the outflow no additional flow resistance.

Abstract

L'invention concerne une éolienne comportant un canal d'écoulement (2) entre deux parois de canal (8), dont au moins une forme une paroi extérieure d'un bâtiment (1), et des turbines éoliennes (3) qui sont montées à l'intérieur du canal d'écoulement (2), réparties sur la hauteur de ce dernier et traversées axialement par le vent. L'objectif de l'invention est d'assurer des conditions d'écoulement favorables dans le canal d'écoulement (2). A cet effet, selon l'invention, une unité de guidage (11), comportant des parois de guidage (12) se trouvant face à face par rapport au canal d'écoulement (2) et pouvant pivoter indépendamment les unes des autres, est montée en amont des turbines éoliennes (3) individuelles dans le sens d'écoulement (18) du vent, lesdites parois de guidage étant montées de manière à pouvoir pivoter sur la paroi de canal (8) associée, au niveau de leur face frontale (13) opposée à la turbine éolienne (3), et pouvant être déplacées au moins progressivement entre une position initiale s'étendant sensiblement en direction de la paroi de canal (8) associée et une position finale dans laquelle elles pivotent les unes vers les autres et ferment le canal d'écoulement (2).
