Title (EN) WATER TURBINE IN TETHERED ASYMMETRIC NOZZLE
(FR) TURBINE HYDRAULIQUE A BUSE ASYMETRIQUE CAPTIVE
Abstract:
(EN) The object of description is an energy generating device for harnessing submarine currents composed of an asymmetric nozzle capable of directing the water flow towards one or more turbines placed (5) before the said nozzle's outlet (4). The nozzle's inlet is asymmetric in shape; one surface of the aforementioned inlet extends beyond its opposite surface, thus acting as a lifting surface producing a force with a component perpendicular to the current flow. The device is moored with a tether-line system (7) which enables the said device to remain in equilibrium, by counteracting the vertical component of the tether' s tension, with the vertical lift due to the water flowing through the asymmetric nozzle.
(FR) Cette invention concerne un dispositif générateur d'énergie conçu pour maîtriser des courants sous-marins, qui est composé d'une buse asymétrique capable de diriger le flux de l'eau vers une ou plusieurs turbines implantées (5) en avant de la sortie de buse (4). L'admission de la buse présente une forme asymétrique: une des surfaces de ladite admission, qui dépasse par rapport à la surface opposée, agit comme une surface de levage qui produit une force avec une composante perpendiculaire au sens du flux. Le dispositif est ancré au moyen d'un système de câbles (7) qui lui permet de rester en équilibre en s'opposant à la composante verticale de la tension des câbles, le levage vertical étant causé par l'écoulement de l'eau à travers la buse asymétrique.
