Abstract

Wind and hydro turbine turbulence control mechanism with an accelerating ring 21 and vortex stabilisers 22 around the back nacelle 20 to reduce the blades rotation turbulence. There may also be multiple accelerator rings and directors 8 around the turbine housing, where the directors could be vertical and with radii. The multiple accelerator rings may be positioned such that the additional accelerator rings vertically align or misalign with the front edge of the primary accelerator ring. A wind and hydro turbines turbulence control mechanism with only directors is also claimed. The application relates to a wind or water turbine with wind affecting elements behind the turbine that is intended to affect the wind vortex leaving the back of the turbine.

Description

Wind and hydro turbines turbulence control mechanism
Background
This invention relate to new ways of controlling turbulence made by wind or hydro electro generating turbines blades rotation.
At the moment most of the turbulence control considering fluid flow over turbines blades is done by specific design of blades its selves, but in case of this invention that control is further augmented on a very different way.
Statement of invention
In this case turbulence control is achieved by adding accelerating ring around back (exit) side of turbine nacelle along with rings stabilizing wings by which accelerating ring is connected with turbine nacelle. The accelerating ring accelerate fluid vortex behind turbine rotor or rotors (if turbine have more than one rotor) blades and by means of rings vertical stabilizers, stabilize and corrects turbulent fluid movement behind blades and thus make flow of fluid trough turbine blades much easier and faster. On this way overall turbine efficiency and productivity is increased. At cross section shape of the accelerating ring could be either with each external and internal sides flat with rounded corners, or with one side flat one convex or both side convex as presented on images within this application. The shape number and distribution of ring's stabilizing wings could also be various. Accelerating ring with stabilizing wings around back, exit, side of turbine nacelle (turbulence control mechanism) could be implemented on any type of rotor and blades based types turbines both shrouded (with or without ducts) and conventional non shrouded. If turbine is shrouded and do not have nacelle (like some types of turbines with electro generators made around turbines rotors and blades) in that case accelerator ring could be connected directly with turbine shrouding housing with additional vertical supporters i.e. stabilizers outside accelerating ring. In that case accelerating ring could also have additional cylindrical or conical or convex lens like shaped element inside accelerating ring, parallel with rotors rotation axis, for additional fluid acceleration.
Within images in this patent applications is presented form of turbulence control mechanism consisting from only one ring with stabilizing wings around exit part of turbine nacelle but turbulence control mechanism could consists one, two or more additional accelerating rings and additional stabilizing wings around primary accelerating ring. Position of these additional rings could in same line with primary acceleration ring or they could be outside of line of primary acceleration ring position. At cross section shape these accelerating rings could be either with each external and internal sides flat with rounded corners, or with one side flat one convex or both side convex as presented on images within this application. Within this application are presented implementation examples of turbulence control system on turbines with advanced turbine housings (shrouds) as described in patent application PCT/RS/2012/00005. In addition for further fluid acceleration as additional part of those housings and as addition in turbulence control outside turbines housings could be placed directors connected with housings. These directors could be at various shapes, number and position relative to turbine housings.

Detailed description
Wind and hydro turbines turbulence control mechanism works by having accelerating ring 21 around back (exit) 20 side of turbine nacelle 20 along with rings 21 stabilizing wings 22 by which accelerating ring 21 is connected with turbine nacelle 20. The accelerating ring 21 accelerate fluid vortex behind turbine rotor or rotors 10, 11 (if turbine have more than one rotor) blades 12, 13 and by means of rings 21 stabilizing wings 22, stabilize and corrects turbulent fluid movement behind blades 12, 13 and thus make flow of fluid behind and trough turbine blades 12, 13 much easier and faster. On this way overall turbine efficiency and productivity is increased. At cross section shape of the accelerating ring 21 could be either with each external and internal sides flat with rounded corners, or with one side flat one convex or both side convex as presented on images within this application.
The shape number and distribution of ring's 21 stabilizing wings 22 could also be various.
Accelerating ring 21 with stabilizing wings 22 around back, exit, side of turbine nacelle 20 (turbulence control mechanism) could be implemented on any type of rotor and blades based types turbines both shrouded (with or without ducts) and conventional non shrouded. If turbine is shrouded and do not have nacelle 9, 20 (like some types of turbines with electro generators made around turbines rotors and blades) in that case accelerator ring could be connected directly with turbine shrouding housing 1,2,3 with additional vertical supporters i.e. stabilizers outside accelerating ring. In that case accelerating ring could also have additional cylindrical or conical or convex lens like shaped element inside accelerating ring, parallel with rotors rotation axis, for additional fluid acceleration. Front nacelle 9 means that this nacelle is first on fluid flow path.
Within images in this patent application is presented form of turbulence control mechanism consisting from only one ring 21 with stabilizing wings 22 around exit part of turbine nacelle 20 but turbulence control mechanism could consists one, two or more additional accelerating rings 23 and additional stabilizing wings 25 around primary accelerating ring 21. Position of these additional rings 23 could be in same parallel vertical line with primary acceleration ring 21 (front edge of ring 23 aligned with front edge of ring 21) or they could be outside of parallel vertical line of primary acceleration ring 21 position as presented in this case on figure 4. At cross section shape these accelerating rings 23 could be either with each external and internal sides flat with rounded corners, or with one side flat one convex or both side convex as presented on images within this application.
Within this application are presented implementation examples of turbulence control system on turbines with advanced turbine housings (shrouds) as described in patent application PCT/RS/2012/00005. In addition for further fluid acceleration as additional part of those housings and as addition in turbulence control outside turbines housings could be placed directors 8 connected with housings. These directors 8 could be at various shapes, number and position relative to turbine housings. Each of variant of turbines housings (shrouds) with directors 8 presented on figures to figure 16 could also have turbulence control mechanism with one or more than one accelerating ring 21 with stabilizing wings 22 along with directors 8. Each of variants of turbines presented on figures from figures to figure 16 could have turbulence control mechanism with one or more than one accelerating ring 21 with stabilizing wings 22 without directors 8.
On pictures within this application, outside additions such as turbulence control mechanism or directors 8, is presented base wind or hydro turbine variant with two contra rotating rotors 10, 11 with blades 12, 13, with corresponding front nacelle 9 and back nacelle 20 with different variants of housings (shrouds). On figures 1-10 turbines housing consists from primary shrouding tube 1 with ducts 2,3 connected with horizontal radii ring 6 by stabilizers 4. At the top of the ring 6 are placed stabilizers 7. On figures 11, 12 is presented same turbine with same housing with addition of vertical rings 14, 15 at the top of radii ring 6. On figures 13 and 15 is presented same turbine with housing consist from primary shrouding tube 1 with ducts 2,3 with stabilizers 4 and vertical rings 16, 17, 18 at the top of duct 3. On figures 14 and 16 is presented same turbine with housing consist from primary shrouding tube 1 with ducts 2,3 with stabilizers 4 and vertical ring 16 at the top of duct 3. As previously stated each of these turbine variants could have turbulence control mechanism with ring 21, stabilizers 22 or ring 21, stabilizers 22 and ring 23 with stabilizers 25 around back nacelle 20 and directors 8, connected with housing with stabilizer 5, or just turbulence control mechanism with ring 21, stabilizers 22 or ring 21, stabilizers 22 and ring 23 with stabilizers 25 around back nacelle 20 without directors 8 or just directors 8, connected with housing with stabilizers without turbulence control mechanism with ring 21, stabilizers 22 or ring 21, stabilizers 22 and ring 23 with stabilizers 25 around back nacelle 20.
