摘要： An annular axial rotor for a turbine. The rotor includes a hub structure having a hub diameter and attached to a rotating shaft of the turbine. The rotor also has a plurality of turbine blades extending radially from the hub structure, and at least one annular shroud surrounding the plurality of turbine blades. The annular shroud has a first annular shroud diameter. The turbine blades are held between the hub structure and the annular shroud and the hub diameter is at least 0.3 times the shroud diameter. This configuration greatly facilitates the use of a plurality of airfoils to adjust the solidity and the tip speed ratio of the rotor. This can be achieved while maintaining a high coefficient for the conversion of fluid energy into useful torque.

摘要： A fluid turbine apparatus for use with a turbine comprising a convergent section, a fluid turbine section adjacent to an outlet of the convergent section, and a divergent section adjacent to the fluid turbine section. The fluid enters through the convergent section and exits through the divergent section. The convergent and divergent sections are constructed using a modular grid-like structure supporting retractable wall panels. The internal vacuum created by the diffuser and the wind shear stresses on the convergent and divergent sections can be limited. Configurations of the convergent and divergent sections can be adjusted to suit prevailing wind velocities. Barriers of rotating deflectors are used to increase the effective area of the convergent and divergent sections during low wind conditions. Horizontally mounted aerodynamic deflectors may be used to decrease wind shear and drag on the divergent section, the turbine section, and on side walls of the convergent section.

摘要： An annular single or multi-rotor double-walled turbine. The turbine includes an outer shroud, an inner shroud, and a plurality of driveshafts. The turbine also includes a plurality of rotors coaxially attached to the plurality of driveshafts at spaced intervals. Each of the plurality of rotors comprises a plurality of turbine blades extending between the inner and outer shrouds. Each of the plurality of turbine blades comprises a face. The inner shroud and the outer shroud form a continuous channel for directing a fluid entering the turbine towards the faces of the turbine blades and for directing fluid discharged from a first of the plurality of rotors to the remaining rotors. The channel greatly improves efficiency of power extraction from all augmented and non-augmented fluid streams.

摘要： A directing system for directing fluid entering an axial flow turbine along an inlet flow direction. The turbine includes a plurality of turbine blades. The directing system includes a base structure, a plurality of directing segments attached to the base structure, downstream of the base structure, and a directing segment adjustment system for adjustably positioning the directing segments between a retracted configuration and a deployed configuration. The directing segments, in the deployed configuration, extend beyond the base structure in a direction transversal to the inlet flow direction and deflect the fluid towards an outer circumference of the plurality of turbine blades corresponding to a higher torque area of the blades. A directing system for directing fluid entering a cross-flow turbine is also disclosed. In the cross-flow turbine, the fluid is directed towards a centerline of the rotor of the turbine, which is a high torque area of the turbine blades.

摘要： 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.
