Description
Wind Turbine The present invention relates to a wind turbine for
generating electrical power from wind.
Wind turbines are known, consisting of rotary engines configured to extract energy from the wind. Aerofoils are used to generate lift from the moving wind and to impart this onto a rotor, thereby operating as a reaction turbine. In addition, the turbine also gains some energy from the impulse of the wind, by deflecting the wind at an angle.
* A problem with known wind turbine devices is that they require substantial areas of land and are not considered to be compatible with standard urban configurations. This is unfortunate given that many urban settings, particularly when relatively high building are present, experience significant windy conditions thereby presenting a source of energy that could be harnessed, if it were possible to establish a suitable turbine configuration without changing the overall look of the working environment.
According to an aspect of the present invention, there is provided a wind turbine apparatus for generating power from wind, comprising: a rotor with blades rotatable about an axis in response to wind acting upon said -* blades and positionable on a roof of a building with said axis of rotation being substantially in line with an edge of said building; and a fairing positionable on said edge to present a curved surface to the flow of air and to direct wind onto said rotor.
In a preferred embodiment, the roof is substantially flat.
In a first embodiment, the fairing is configured to direct wind towards the blades of the rotor at a lower half of said rotor so as to effect rotation of said rotor in a first direction.
In an alternative embodiment, the fairing is configured to direct wind towards the blades of the rotor at an upper half of said rotor so as to effect rotation in a second direction.
In a preferred embodiment, a first rotor is configured to rotate in a first direction and a second rotor is configured to rotate in a second direction.
According to a second aspect of the present invention, there is provided a method of extracting energy from wind, comprising the steps of: securing a wind turbine to the roof of a building in which a rotor has a plurality of blades that rotate about an axis and said axis is placed substantially in line with an Sedge of said building; and positioning a fairing on said edge so as to direct wind onto said rotor.
The invention will now be described by way of example only, with reference to the accompanying drawings, of which: Figure 1 shows a relatively high building facility with a flat roof; Figure 2 illustrates a wind turbine apparatus; Figure 3 shows an alternative wind turbine apparatus Figure 4 shows the building of Figure 1 with wind turbine apparatus attached thereto.
A building facility is shown in Figure 1 that is relatively high and has flat * roof 101. The building includes a doorway 102 of substantially standard size and a plurality of large windows 103. The building includes many electrically powered systems, such as lighting systems, heating/cooling systems and data processing systems etc. Consequently, the activities performed within the building result in a significant consumption of electrical power.
It is appreciated that a prevailing wind often blows in the direction of arrow 104 and it is also appreciated that wind turbines could be used to extract usable energy from the fluid flow of the wind.
From the perspective of a turbine, the wind constitutes a working fluid that contains potential energy (a pressure head) and kinetic energy a velocity head. The rotary engine of the turbine uses an aerofoil to generate lift from the moving fluid and to impart this lift upon the rotor (a form of reaction) in addition to gaining some energy from the impulse of the wind by deflecting it at an angle, hence providing a form of impulse turbine.
Impulse turbines change the direction of flow of a high velocity fluid such that the resulting impulse spins the turbine and leaves the fluid with diminished kinetic energy. Reaction turbines develop torque by reacting with the fluid's pressure or weight and the pressure of the fluid changes as it passes through the turbine blades.
Thus, engineering techniques are known for extracting energy contained within wind and converting it, via rotational mechanisms, into electrical energy for possible consumption within the building, thereby reducing demands placed on external sources. However, problems exist in terms of incorporating such a device within the design of the building without dramatically changing the overall appearance of the building and thereby detracting from its primary role. Figure 2 A wind turbine apparatus is illustrated in Figure 2, configured to generate power from wind. The wind turbine includes a rotor 201 that has blades 202 such that the rotor is rotatable about an axis 203 in response to wind acting upon blades 202.
An aerofoil 204 is provided at the end of each of said blades and it is primarily the reaction of the wind with respect to these aerofoils that results in the transfer of energy from the wind to the rotating turbine.
The turbine apparatus is located by a mounting 205 onto the roof 101 of the building illustrated in Figure 1, for example. The mounting 205 is positioned close to an edge 206 of the building, with the axis of rotation 203 being substantially in line with the edge 206. Furthermore, a fairing 207 is positioned on edge 206 to present a curved surface to the flow of air and to direct the wind onto the rotor 201.
A substantial proportion of the wind that flows over the roof 101 of the building is derived from lower levels (flowing in the direction of arrow 104) and is then forced on to the roof by a wind facing wall 208 until the wind reaches the wind facing edge 206. In the embodiment shown in Figure 2, the fairing 207 is configured to direct wind towards the blades of the rotor at a lower half of the rotor so as to effect rotation of the rotor in a first direction. As shown in Figure 2, this first direction is a clockwise direction and the aerofoils 204 are arranged for operation in this clockwise direction.
The fairing 207 defines a first convex surface 209 at the edge 206 of the building. In addition, the fairing 207 defines a first concave surface 210 that extends from said first convex surface 209 to meet with the roof 101.
Furthermore, a second concave surface 211 extends from said first convex surface 209 so as to extend substantially vertically over wall 208. In this way, as illustrated by arrows 212, wind brought up the waIl 208 of the building is directed around the fairing and towards the lower half of the rotor 201 thereby * effecting rotation of the rotor in a clockwise direction. Figure 3 An alternative wind turbine apparatus is illustrated in Figure 3, again configured to generate power from the wind. The wind turbine includes a rotor 301 that has blades 302 such that the rotor is rotatable about an axis 303 in response to wind acting upon the blades 302.
An aerofoil 304 is provided at the end of each of the blades 302.
In a similar configuration to the apparatus shown in Figure 2, the turbine apparatus is located by a mounting 305 on to the roof of the building. Again, the mounting 205 is positioned close to an edge to 306 of the building, with the axis of rotation 303 being substantially inline with the edge 306. A fairing 307 is positioned at edge 306 to present a curved surface to the flow of air and to direct the wind onto the rotor 301.
In the embodiment shown in Figure 3, the fairing 307 is configured to direct wind towards the blades of the rotor at an upper half of the rotor so as to effect rotation of the rotor in a second direction. As shown in Figure 3, this second direction is a counter clockwise direction and the aerofoils 304 are arranged for operation in this counter clockwise direction.
* The fairing 307 defines a first convex surface 309 at the edge 306 of the building. The fairing 307 also defines a first concave surface 310 that extends from the first convex surface 309 in a substantially upwards direction.
In addition, a second concave surface 311 extends form the first convex surface 309 substantially vertically over the wall of the building. In this way, as illustrated by arrows 312, wind brought up the wall 208 of the building is directed around the fairing and towards the upper half of the rotor 301 thereby effecting rotation of the rotor in a counter clockwise direction.
The building of Figure 1 is also shown in Figure 4, having a wind turbine apparatus 402 of the type shown in Figure 2 and a wind turbine apparatus 403 * of the type shown in Figure 3. In response to wind travelling over the building, as illustrated by arrows 404, turbine 402 is forced to rotate in a clockwise direction and turbine 403 is forced to rotate in a counter clockwise direction.
An electrical generator 405 is positioned between the turbines 402 and 403 such that a first portion of the generator is rotated in a first direction and a second portion of the generator is rotated in a second direction. In this way, the relative rotational speeds within the generator itself are increased, thereby improving generation efficiency. In order to minimise the drag caused by the presence of the generator, the generator itself is enclosed within a cowling or nacelle. Further attributes for electrical generators operating in accordance with this configuration are disclosed in the present applicant's British patent No 2 402 976 and United States patent applications 10/559,589 and 10/559,591 the whole contents of which are enclosed herein by reference.
