Title
(EN) TURBINE APPARATUS
(FR) APPAREIL DE TURBINE
Abstract
(EN) A fluid turbine apparatus which is able to increase the fluid velocity and consequently increase the rotation speed of the fluid turbine. The fluid turbine apparatus has a convergent section, a fluid turbine section and a divergent section. The fluid enters into the fluid turbine through the convergent section, passes through the fluid turbine and exits through the divergent section. The combination of the convergent section and the divergent section creates a Venturi effect and increases the fluid velocity and thus the energy density entering turbine for increasing the energy extracted by the turbine.
(FR) L'invention porte sur un appareil de turbine à fluide qui est apte à augmenter la vitesse de fluide et, par conséquent, à augmenter la vitesse de rotation de la turbine à fluide. L'appareil de turbine à fluide comprend une section convergente, une section de turbine à fluide et une section divergente. Le fluide entre dans la turbine à fluide à travers la section convergente, traverse la turbine à fluide et sort à travers la section divergente. La combinaison de la section convergente et de la section divergente crée un effet Venturi et augmente la vitesse du fluide et, ainsi, la densité d'énergie entrant dans la turbine pour augmenter l'énergie extraite par la turbine.
