Dolor neuropatico fisiopatologia The duct 40 may be a cylinder of constant or converging internal diameter, or, optionally, the interior walls may diverge in order to increase the mass flow of water flowing through the duct 40. Additionally, the duct 40 includes an opening at the intake end or inlet 42 and an opening at the outflow end 20 or outlet 44. In a particular embodiment the inlet 42 is circular in an elevation view and the outlet 44 is oblong, in order to minimize the height profile of the turbine 10 in potentially relatively shallow sites, or sites with navigational clearance restrictions (such as rivers or seaways for example) while maximizing flow, turbine blade diameter and therefore power output. In an optional embodiment, the interior walls of the hub 20 may converge in order to increase the velocity of water flowing through the longitudinal hole in a venturi effect. The central hub preferably includes a 5 longitudinal hole defined by the interior walls of the hub 20. The interior walls of the hub 20 may form a cylinder of constant internal diameter.

There is a need therefore for a unidirectional hydro turbine generator which provides improved efficiency and performance of the turbine and generator components, for improved reliability and longevity in aggressive and/or corrosive submerged operating environments, or for reduced complexity and cost of manufacture, operation or maintenance. The unidirectional turbine generator unit 10 with diffuser duct may be used as a single turbine generator unit 10 or with a plurality of turbine generator units 10, typically deployed in river environments, although the design may be used in other environments such as sub-sea tidal areas, tail-races or in wind energy units. Therefore the geometric range of (Autict/Ainet) for the duct 40 disclosed above may desirably provide benefits including one or more of: reducing the structural load imposed on the generator by the duct 40, reducing hydrodynamic drag due to the duct 40, reducing 15 manufacturing, deployment and maintenance/replacement cost of the duct 40, reducing overall depth and length of the duct 40, and reducing generation of downstream turbulence, which may also desirably reduce the effect of an upstream generator unit on one or more downstream units such as in a generator array or farm configuration, thereby providing for optimal exploitation of a unidirectional fluid flow resource.

More particularly, the present invention relates to hydro turbines adapted for use in unidirectional water flows and having enhanced 15 outer duct arrangements, turbine blade designs, and magnetic generator configurations, and an arrangement for connecting such turbines to an electrical distribution system. 10 2. Dolor muscular en todo el cuerpo . TECHNICAL FIELD The present invention relates generally to unidirectional hydro turbines adapted for use in unidirectional water flow environments. The Davis reference also discloses a hydro turbine with a dual-sided axial-flux magnetic generator adapted for use in bidirectional fluid flow applications. A hub 20 with an axis substantially parallel to the direction of water flow 100 is disposed along the central longitudinal axis of the turbine generator 10. The hub 20 has a hub nose 21 at the inlet end which may be advantageously formed in any hydrodynamic shape. 20 The flared feature or diverging diameter of the duct 40 may be described by a geometric relationship which maximizes the diffusion efficiency of the duct.

Design characteristics of the 25 duct 40 have been determined and are herein disclosed which exhibit optimal flow and therefore power generation characteristics. The longitudinal or central hole functions to reduce the resulting flow separation downstream of the hub 20 and therefore increases the total mass flow through the turbine annulus or flow area. 25 The turbine generator unit 10 has two ends about a center line, with an intake, upstream or inlet end on one hand, and an outflow, downstream or outlet end on the other. FIG. 2 illustrates the profile of the inner surface of the duct 40 from the start of the flare section of the duct to the downstream or outlet edge. Another object of certain embodiments of the present invention is to provide a low profile design for efficient operation in shallow fluid streams or areas of low water depth.
