Title: (DE) VORRICHTUNG ZUR VERWENDUNG VON WELLENENERGIE UND VERFAHREN
(EN) A DEVICE FOR THE UTILISATION OF WAVE ENERGY AND A METHOD
(FR) DISPOSITIF PERMETTANT DE RÉCUPÉRER L'ÉNERGIE DE LA HOULE ET PROCÉDÉ ASSOCIÉ
Abstract:
(EN) The invention relates to a device for the utilisation of wave energy, with an increased efficiency. Thereto, the device according to the invention comprises - a Darrieus rotor having at least two Darrieus rotor blades, wherein the Darrieus rotor has a solidity σD, and - a Wells rotor having at least two Wells rotor blades, wherein the Wells rotor has a solidity σW, wherein - the Darrieus rotor and the Wells rotor are rotatable about a common axis of rotation A, and - σW is larger than or equal to σD. The invention also relates to a method for harnessing wave en¬ ergy.
(FR) L’invention concerne un dispositif permettant de récupérer l’énergie de la houle avec un rendement accru, qui comprend : - un rotor Darrieus à au moins deux pales de rotor Darrieus, le rotor Darrieus possédant un coefficient de plénitude σD, et – un rotor Wells à au moins deux pales de rotor Wells, le rotor Wells possédant un coefficient de plénitude σW. Le rotor Darrieus et le rotor Wells sont rotatifs autour d’un axe de rotation commun A, et σW est supérieur ou égal à σD. L’invention concerne également un procédé permettant de récupérer l’énergie de la houle.
