Abstract: front page image
(EN)The preformance of a turbine (3) for harnessing energy from a fluid stream is enhanced by increasing the speed of fluid flowing over the blades of the turbine. For this purpose a rotor (9) is driven by the fluid stream and has means for extracting fluid from the downstream side of the turbine. The turbine (3) and rotor (9) are driven by distinct fluid streams, which are separated by a duct (1).
(FR)Selon la présente invention, l'efficacité d'une turbine (3) destinée à capter l'énergie d'un courant de fluide, est améliorée grâce à l'augmentation de la vitesse du fluide circulant sur les pales de la turbine. A cet effet, un rotor (9) est entraîné par le courant de fluide et présente un système destiné à extraire le fluide du côté aval de la turbine. La turbine (3) et le rotor (9) sont entraînés par des courants de fluide distincts qui sont séparés par une canalisation (1).
