Definitions
- TECHNICAL FIELD relates to a turbine for recovering energy from a fluid stream, in particular, the invention concerns a diffuser augmented fluid-driven turbine having a fabric shroud.
- the invention has been primarily developed for use in recovering energy from air streams and will therefore be described in this context. However, it is to be appreciated that the invention can also be used to recover energy from other fluid streams, such as water currents. BACKGROUND ART
- Diffuser augmented wind turbines characteristically comprise wind-driven rotor blades housed within a throat of a shroud, the shroud having an air intake section that converges towards the throat and an air outlet section (diffuser section) that diverges from the throat.
- the conical shape of the diffuser section helps air that has passed through the rotor blades (ie. turbine wake) to remain at a pressure below atmospheric pressure, thus encouraging more air to be drawn through the blades.
- the wake As the wake flows towards an exit of the diffuser section it gradually undergoes a change back to atmospheric pressure. This event can cause the wake to separate from an inner surface of the diffuser section (ie.
- boundary layer separation and consequently to reduce turbine efficiency. It is possible to minimize this event by reducing the included angle of the conical section or by channeling air from outside of the shroud directly into the diffuser section for re-energizing the boundary layer. This can also provide an additional power augmentation effect to the turbine.
- a diffuser augmented fluid-driven turbine comprising: fluid-driven rotor blades contained in a housing; at least one support ring assembly spaced from said housing and axially mounted with respect to said blades; a fabric shroud extending between said housing and said support ring assembly that when tensioned forms a diffuser section; and a spar assembly about which said blades rotate, with said spar assembly extending axially to said blades, and said housing and/or support ring assembly are adjustably mounted to said spar assembly so that said shroud can be tensioned.
- the spar assembly can have a passage for channeling fluid into the diffuser section for mixing with a wake of the turbine, without having to pass through the rotor blades, so as to minimize premature separation of the wake from an inner surface of the diffuser section and also to provide a power augmentation effect.
- the passage can have an inlet upstream of the blades and at least one outlet within the diffuser section. Preferably, the passage has multiple outlets.
- the flow of fluid through the passage outlet can be regulated by varying the size of the outlet.
- the size of the outlet can be varied by a slideable collar mounted to the spar assembly.
- the collar can be slid manually, or, for instance, using hydraulic or pneumatic means. If desired, the collar can have projections for creating additional turbulence in the fluid flowing through the outlet, which can result in enhanced mixing with the turbine wake.
- the blade housing can have a blade retaining ring for keeping the shroud from contacting the rotor blades and a plurality of stator blades for mounting the blade retaining ring to the spar assembly.
- the housing is rigidly mounted to the spar assembly.
- the stator blades can be adjusted to direct the flow of fluid to the rotor blades.
- the diffuser augmented fluid-driven turbine can have a plurality of blades mounted for rotation about the spar assembly. Rotation can be effected with bearings.
- the blades can rotate with at least one portion of the spar assembly. For instance, a portion of the spar assembly that has the passage outlet can rotate with the blades relative to the remainder of the spar assembly.
- the diffuser augmented fluid-driven turbine can be coupled in numerous ways to machinery for generating electrical or mechanical energy from the recovered energy.
- the rotor blades can be coupled to an electric generator by way of a gear assembly.
- the support ring assembly can comprise: a ring that is attached to the shroud; a collar that is slideably mounted to the spar assembly; a first set of radial stays that attach the collar to the ring within the plane of the ring; and, a second set of radial stays that adjustably attach the ring to a region of the spar assembly located outside the shroud.
- the second set of radial stays are attached to a cap that is adjustably mounted to an end of the spar assembly, and the shroud is tensioned by increasing the distance between the cap and the spar assembly end.
- the cap can be mounted by any suitable method, but preferably, by adjustably bolting the cap to the spar assembly end.
- the shroud can be tensioned in others ways.
- the length of the second set of stays of the support ring assembly can be shortened, perhaps by using turnbuckles, instead of adjusting the position of the cap.
- the spar assembly can be adjusted in length to tension the shroud.
- a portion of the spar assembly between the first and second sets of radial stays could be lengthened to tension the shroud and shortened to relax the shroud.
- the diffuser augmented fluid-driven turbine can have a further support ring assembly adjustably mounted to the spar assembly and spaced from the blade housing, and the shroud can extend between the housing and a ring of the further support ring assembly.
- the further support ring assembly can be mounted to the spar assembly as for the support ring assembly of the diffuser section.
- the shroud between the further support ring assembly and the housing can form a fluid intake section having an inner surface converging towards the housing.
- the fluid inlet of the spar assembly is located upstream of the fluid intake section of the shroud.
- the diffuser augmented fluid-driven turbine is lightweight yet sufficiently strong to tolerate strong fluid streams.
- the fluid stream can comprise an air current or a water current.
- the turbine is most suitable for recovering energy from wind.
- the ring of the support ring assembly and spar assembly are of substantially hollow construction and that they comprise high strength material, such as steel.
- the stays of the support ring assembly can be tensioned cables of any suitable material, or if desired, the stays can be rigid, perhaps tubular sections.
- the diffuser augmented fluid- driven turbine can be submerged facing into the flow, as for recovering energy from wind.
- the turbine should be constructed of materials that are tolerant of marine conditions and the turbine may lack an air intake section.
- the diffuser augmented fluid-driven turbine can be mounted on top of a suitably designed chamber. Waves flowing into the chamber can force air out of the chamber through the turbine. As the wave recedes, the opposite occurs.
- the shroud can consist of any thin, flexible material made of any combination of cloth, fiber, polymeric film, sheet or foam, and is preferably a durable, weatherproof and lightweight fabric, such as PVC coated polyester.
- the shroud can be prefabricated so that when tensioned it adopts an appropriate "hourglass" shape, compete with sections that form the fluid intake section, the throat and the diffuser section. In this instance, the shroud need not necessarily be attached to the blade retaining ring.
- the shroud can be attached to the ring of the support ring assembly using any suitable means, for instance, by stitching an edge of the fabric, or strengthened edge of the fabric to the ring or by clamping the fabric between a two-piece ring having identical halves.
- the stays of the support ring assembly can be attached to the collar or spar assembly by any suitable means, such as a shackle arrangement, or lugs with eyes.
- a sheath can be used to envelop the shroud so that drag forces on an outer surface of the diffuser section are reduced.
- fabric of substantially cylindrical shape can be tensioned between the rings of the support ring assemblies such that the hourglass shape of the shroud is cloaked from the fluid current.
- the diffuser augmented fluid-driven turbine can be supported by a ground-supporting structure by attaching the rings of the support ring assemblies to support arms of the structure.
- the ground supporting structure can have other points of contact with the turbine.
- a support arm can be further attached to the blade housing through the shroud to minimize the effect of rotor imbalance.
- the blade housing, ring/s and spar assembly can be attached to the support arms in a number of ways, but a preferred way is the use of brackets fitted to the rings of the support ring assemblies and/or blade housing, whereby the brackets can accommodate movement of the rings when tensioning the shroud. If the turbine has only one support ring assembly, then a further point of contact is preferably at the blade housing.

- FIG. 1 there is shown a diffuser augmented wind turbine 1 ("wind turbine") attached to a ground-supporting tower 2 according to an embodiment of the invention.
- the wind turbine 1 comprises: wind-driven rotor blades 3 contained in a housing 4, 5; two support ring assemblies 8, 10, 11 and 7, 10, 11 positioned on either side of the housing 4, 5 and axially mounted with respect to the blades 3; a fabric shroud 6 extending between rings 7 and 8 of the support ring assemblies; and, a spar assembly 9 that extends longitudinally to the blades 3 and which is adjustably mounted to rings 7 and 8.
- the wind turbine 1 has blades 3 in a housing comprising a blade retaining ring 4, that stops the shroud 6 from contacting the blades 3, and a plurality of stator blades 5 for mounting the blade retaining ring 4 to the spar assembly 9.
- the blades 3 rotate about the spar assembly 9.
- Figures 1 and 2 show that the shroud 6 can be tensioned to form an air intake section 14 between ring 8 and retaining ring 4, and a diffuser section 15 between retaining ring 4 and ring 7.
- the air intake section 14 has an inner surface 22 converging towards retaining ring 4 and the diffuser section 15 has an inner surface 23 diverging away from retaining ring 4.
- FIGs 1 and 10 which represent different embodiments of the wind turbine 1 , illustrate that the shroud 6 can be attached to the retaining ring 4.
- Figure 3 which represents another embodiment of the wind turbine 1 , shows that the shroud 6 is not attached to the retaining ring 4. However, in this case, the shroud 6 would be prefabricated so that when tensioned it will form the air intake section 14, diffuser section 15 and throat.
- FIG. 3 shows further details of the support ring assemblies 8, 10, 11 and 7, 10, 11 that were only partly illustrated in Figures 1 and 2.
- Each support ring assembly comprises: a ring (7 or 8) that is attached to the shroud 6; a collar 16 that is slideably mounted to the spar assembly 9; a first set of radial stays 10 that attach the collar 16 to the ring (7 or 8) within the plane of the ring (7 or 8); and, a second set of stays 11 that are attached to end 27 or end 32 of the spar assembly 9.
- FIG. 2 shows that the collar 16 has lugs 43 with eyes 44 from which extend the stays 10.
- Each ring 7, 8 has a number of attached lugs 19 that have a first eye 20 for attaching to a stay of the first set of stays 10 and a second eye 21 for attaching to a stay of the second set of stays 11.
- FIG 3 shows that stays 11 , located near the diffuser section 15, are attached to an adjustably mounted cap 24 that engages spar assembly end 27.
- the cap 24 has lugs 25 with eyes 26 from which extend stays 11.
- the shroud 6 is tensioned by increasing the distance between the cap 24 and end 27.
- Better views of how cap 24 can be mounted to end 27 are shown in Figures 4 and 5.
- the distance between the cap 24 and end 27 can be adjusted by screwing retaining nuts 29 along bolts 28.
- the second set of stays 11 extending from ring 8 can be attached to spar assembly end 32 by means of lugs 30 with eyes 31.
- spar assembly end 32 has a passage 33 for injecting air into the diffuser section 15 for mixing with the wake of the turbine, without having to pass through the rotating blades 3, so as to minimize premature separation of the wake from the inner surface 23 of the diffuser section 15 and also to provide a power augmentation effect.
- the passage 33 extends longitudinally within the spar assembly 9 and has an inlet
- the inlet 34 is located upstream of the blades 3.
- Figures 3, 6 and 8 represent different embodiments of the spar assembly 9. The construction of the spar assembly 9 depends on how the blades 3 are to rotate about the spar assembly 9 and how the passage outlets
- Figure 35 are to be configured.
- a portion 45 of the spar assembly 9 having the passage outlets 35 also has a hub 46 of the blades 3.
- Blades 3 are attached to the hub 46 with fasteners that pass through apertures 48.
- Spar portion 45 rotates about another portion 47 of the spar assembly 9 by means of bearings 49.
- Hub 46 only partially obstructs the air flowing through passage 33, as evident from Figure 9.
- the spar assembly 9 has an adjustably mounted sliding collar 36 that regulates the amount of air that is able to exit the outlets 35.
- This collar 36 does not appear in the embodiment of Figure 3.
- the collar 36 is slid using a hydraulic cylinder 37 that is further attached to the spar assembly 9.
- Figure 6 also shows that the collar 36 has finger-like projections 38 for creating additional turbulence in the exiting air, which can result in enhanced mixing with the turbine wake.
- the spar assembly portion containing passage 33 is attached to the spar assembly portion not containing the passage by a core structural member 42, which in this embodiment produces four separate outlets 35 (best viewed in Figure 7).
- drag forces on an outer surface of the shroud 6 can be reduced by rendering a region between the air intake section 14 and diffuser section 15 substantially cylindrical in shape.
- a tensioned fabric sheath 40 extends from ring 8 to item 39 on shroud 6 at the diffuser section 15.
- the diffuser augmented wind turbine 1 of Figure 1 is supported by a tower 2 at four points of contact with the rings 7, 8, two of which can be seen at items 12 and 13. Details of these contact points are not illustrated but preferably involve adjustable brackets attached to the rings 7, 8.
- Figure 3 illustrates the light weightiness of the wind turbine 1 , as the spar assembly 9 is substantially hollow, rings 7, 8 are hollow (not clearly shown), and the shroud 6 comprises PVC coated polyester.
- FIG 10 there is shown a diffuser augmented wind turbine 1 attached to a ground-supporting tower 2 according to another embodiment of the invention.
- the wind turbine 1 is essentially identical to that of the wind turbine of Figures 1 and 3, except for the fact that it does not have an air intake section 14.
- This wind turbine 1 has four points of contact with the tower 2, two of the contact points being to the blade retaining ring 4 and the other two being to ring 7. Only two points of contact 41 , 13 can be seen in this figure.
