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 housi

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.

What is claimed is: 1. An improved turbine generator including at least one blade and a housing disposed about said turbine, wherein the improvement comprises a slot defined by an outer surface of said housing and an inner surface of an augmentor disposed about said housing, said augmentor having an inlet and an outlet which are substantially similar in area, thereby resulting in enhanced flow characteristics of said turbine generator, and wherein said turbine generator is bi-directional.
