A flow enhancement improvement for an underwater turbine generator (10) is disclosed wherein a longitudinal hole (240) is disposed in the central area (26), typically a hub (20) of the generator (10), and a second, augmentor duct (41), preferably rigid, is disposed about the outer duct (40) or housing of the unit to create a slot (200) area. The slot (200) and hollow hub (20) create areas of smooth, laminar fluid flow. The leading edges of the hub (20) or central ring and the augmentor (41) and outer ducts (40) are elliptical to enhance the fluid dynamics of the structure.
La présente invention concerne une amélioration pour augmenter le débit d'une turbogénératrice sous-marine (10), où un trou longitudinal (240) est placé dans la zone centrale (26), généralement un moyeu de la turbogénératrice (10), et un second élément, une gaine d'augmentation (41) préférablement rigide, est placé près de la gaine extérieure (40), ou du logement de l'unité pour créer une fente (200). Cette fente (200) et le moyeu creux ((20) créent des zones d'écoulement de fluide laminaire sans turbulences. Les bords antérieurs du moyeu (20), ou l'anneau central et la gaine d'augmentation (41) et les gaines extérieures (40) sont de forme elliptique afin d'améliorer la dynamique fluidique de la structure.
