The oscillation of the working element transforms the energy of the fluid flow inside of the duct into movement of the working element which in turn may be converted into another form of energy, for example electricity. The present invention relates to a method and apparatus for generating energy from renewable natural sources of energy, in particular to methods of transforming the kinetic energy of naturally occurring moving fluids, such as wind and river water, into movement of working bodies placed in the path of flow of fluid. The duct 1 has an inlet 10 and an outlet 12. A fricative nozzle portion 14 adjacent the inlet 10 is of uniform external cross-section throughout its length but has an interior wall portion 11 which tapers in cross-section from the inlet 10 at its upstream end towards an intermediate interior wall portion of constricted but uniform cross section, and an interior wall portion 19 which is flared internally towards the outlet 12 at its downstream end.

The walls of the fricative nozzle portion 14 are of uniform thickness throughout. 8 Hz, the thickness 3 of the vane 2 at the axis 6 is between 25 and 30mm. The width 4 of the vane 2 is lOOmm. Preferably, the or each partition is hinged about an axis on the downstream end of the or each partition. A partition or working element is formed by a vane 2 which is pivoted at or towards its downstream end about an axis – 7 – 6 transverse to the direction of flow of fluid through the device 100 on the centre line 16 of the device 100. The pivot axis 6 is located in the expansion chamber or diffuser 7 towards its narrower upstream end.

As the vane 2 swings from side to side, it causes a pulsating stream of fluid downstream of the vane 2 as the channels 212 and 214 on either side of the vane 2 are opened and closed. The first sidewall 212 is arcuate and extends outwardly before curving around an apex and then extending straight towards the turbine 200 which is offset towards the second sidewall 214. The first sidewall 212 extends into a substantially straight sidewall along the centre line 16 of the device 202, forming an outlet 216. The second sidewall 210 has an internal side which is straight and extends outwardly. The external side of the second sidewall 210 also extends straight outwardly at a greater angle to the internal side. A semi-circular sidewall extends around the turbine 200 from the second sidewall 210 to a straight sidewall of an outlet 216 that extends parallel to the centre line 16 of the device.

Fluid entering the device 100 flows in a non-turbulent manner into the device 100. The constriction formed by the intermediate interior wall portion 15 acts on the fluid entering the device 100 to give a Venturi effect that produces a difference in fluid pressure in the two channels 22,24 on either side of the vane 2 when the vane is offset to one side or the other from the median position. This effect causes the vane 2 to swing towards the channel of lower fluid pressure. Preferably, the duct comprises an entrance in the form of a nozzle.
At the downstream end, the interior wall 19 of the nozzle 13 merges into an expansion chamber or diffuser 7 which is flared outwardly, internally and externally towards the outlet 12. Fluid entering the device 100 at the inlet 10 passes through the constriction formed by the interior wall 11 of the nozzle and through the diffuser 7 and leaves the device 100 at the outlet 12 as indicated by the dashed lines 8. Parches para dolor de espalda baja . The fluid may be air such as in a wind powered device or liquid such as water in a river driven device. The form of the duct and the length of the vane may be adjustable to tune the device and improve its effectiveness. Changing the ratio 5 (Figure 5) of the length of the oscillating vane 2 to the width 4 of the duct 1 will change the vane oscillating frequency. Increasing the width 4 of the vane 2 or increasing its length 5. Which is more suitable depends on how the change alters the speed of the flow.

Increasing the rate of movement of the fluid towards the mouth or the opening will lead to a decrease in the Strouhal number. Increasing the speed will increase efficiency. The device 100” has two vanes 2 located on either side of a fixed partition or divider 70. The vanes 2 can both pivot about their respective pivot axes 6. The vanes 2 are each mechanically connected to a common axle or shaft 72 by a respective crank 50. The common axle 72 is connected to a dynamo or other suitable device (not shown) in order to convert the rotary motion of the common axle 72 to electrical energy or other forms of energy. The vane 2 is coupled to a device which converts the movement into other forms of energy. The two turbines 300 and 302 and the vane 2 are each coupled to another device for generating other forms of energy.

In a modification of the invention, one or more turbines are located downstream of the partition. Figure 14 shows a further modification similar to that of Figure 13 but in which two turbines 300 and 302 are located in the fluid flow stream. Terapia del dolor lumbar bloqueo . The higher kinetic energy flow bears the blades of the turbines 300 and 302 to produce sufficient torque on the turbines 300 and 302 to overcome the inherent friction in the turbines 300 and 302 using a lower overall flow rate. According to a first aspect of the present invention, a method for transforming energy in flow in a fluid medium into another form of energy comprises flowing a fluid medium through a duct and over a working surface of a working element of an energy converter so that the flow of fluid induces oscillations of the working element. With a device according to the present invention, it is possible to generate energy with speeds as low as 3.5 to 5.Om per second or even lower.
This kind of regulation of speed of flow is not expedient with wind-powered plants, in view of the complexity, inconvenience and expense of having a regulator. Decreasing speed of flow at the entrance to the inlet 10, i.e. The pulsating movement of the fluid is more effective in actuating turbines, particularly at low fluid flow rates. In one embodiment, the device 100 will start to operate when the fluid moves at speeds of 3.5 to 5.0 metres per second and will produce mechanical energy with 80% efficiency.

A problem with the use of such renewable sources of energy is the low efficiency of known devices for transforming the kinetic energy of the flow of fluid into other forms of energy. Preferably, the or each partition is an aerodynamic surface with a tapered edge facing upstream. The working element forms a moving partition in the duct. The sides of the fixed partition 70 taper at the upstream end. The fixed partition 70 has parallel sides at the downstream end.
The transformation of energy is carried out by the inducement of oscillations of the working element placed in the flow of fluid. We have found that a device 100 can be constructed as described above which converts fluid energy into other forms of energy efficiently and at low flow rates. Preferably, the at least one partition is mechanically connected to an energy converter. The vanes 2 are both mechanically connected to an axle or shaft 78 at their downstream end. The third linkages of these cranks 50, which connect to the common axle 72 are disc shape. The invention in its various aspects is defined in the independent claims below, to which reference should now be made.

Preferably, the or each vane is rectangular in profile. As illustrated in Figure 1, when the fluid pressure in the channel 22 is less than the fluid pressure in the channel 24 the vane 2 swings towards the channel 22. Figure 2 illustrates the situation when the fluid pressure in the channel 22 is greater than the fluid pressure in the channel 24. Dolor muscular generalizado causas . In this situation, the vane 2 swings towards the channel 24. As the vane 2 swings towards one channel, for example channel 22, the pressure of the fluid in both channels is affected. The device 100 comprises a duct 1 of generally rectangular cross-section. The apparatus can work in any fluid medium including gas, liquid, powder, loose material, etc. Oscillations or back and forth movements of the working element are induced automatically by turbulence in the fluid flow and maintained by the oscillating element.
