Dolor de espalda remedio casero

Rather than using a dynamo as described in the present example, the transducer may be a mechanical device that converts the movement of the vane 2 into mechanical energy, for example reciprocating or rotary movement, or it may be a pump which converts the movement into hydraulic energy. The transducer which converts the kinetic energy of the oscillating vane 2 into other forms of energy may vary according to the application.

Exmoor pony 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. The length 5 of the vane 2 is between 350 and 500mm. If the device is intended to function in an air stream, its overall dimension will be about an order of magnitude greater than if it is intended to function in a river. 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. In this embodiment, the interior wall portion 11 of the fricative nozzle portion 14 tapers in cross section from the inlet 10 at its upstream end towards the expansion chamber or diffuser 7 at the downstream end.

The vane 2 extends into the nozzle 13 so that its upstream edge lies in the intermediate portion that forms the constriction. 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. In Figure 13, the upstream arrangement is similar to that of Figures 1 to 5. The upstream arrangement leads to a middle portion 204. The middle portion 204 has a fixed divider 206, with a rectangular cross section, which is spaced from and downstream of the vane 2. The fixed divider 206 is located between two side walls 208 and 210 such that two channels 212 and 214 are formed.

Figure 13 shows another modification of the device 100 of Figures 1 to 5. Downstream of the vane 2 is a turbine 200 which is coupled to another device for generating another form of energy. For example a wind speed of 10 metres per second is required for a conventional device. At speeds of 7 to 8 metres per second, efficiency will reach a maximum value. Sindrome dolor lumbar . 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. 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.

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. A shortcoming of the known devices is the difficulty in achieving efficient use of the energy of the fluid when the speed of flow is low, as is the case, for example, with rivers situated on plains and flatlands, and consequently the dynamic pressure on the blades of the turbine is low. The arrangement of Figure 13 provides the advantage that the pulsating flow rotates the turbine 200 in one direction only and the arrangements is also more effective at rotating the turbine, particularly at low fluid flow speeds. The pulsating movement of the fluid is more effective in actuating turbines, particularly at low fluid flow rates.

In particular, the – 17 position of the turbine or turbines can be varied from those illustrated in order to use the energy from the pulsating flow particularly efficiently and the number of the turbines used can be more than the illustrated number. In a modification of the invention, one or more turbines are located downstream of the partition. Figures 6, 7 and 8 show a modification of the device 100 of Figures 1 to 5. Ejercicios dolor de hombro . It is similar to the device of Figures 1 to 5 and like components have been given the same reference numerals. The two turbines 300 and 302 and the vane 2 are each coupled to another device for generating other forms of energy. 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. The fluid may be air such as in a wind powered device or liquid such as water in a river driven device.

A preferred embodiment of the invention is described in more detail below and takes the form of a method for transforming energy in flow in a fluid medium into another form of energy, the method comprising: 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. In operation, the vane 2 oscillates and the movement of the vane 2 is converted into other forms of energy as in the first embodiment.

The vane 2 will swing towards the channel which has the lower fluid pressure. Abutments can be provided which limit the pivoting movement of the partition about the pivot axis. The apparatus can work in any fluid medium including gas, liquid, powder, loose material, etc. Increasing the Strouhal number leads to an increase in efficiency of the apparatus. 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. 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. The working element forms a moving partition in the duct.
