Abstract

The invention relates to a turbine for oscillating flows, such as the flow produced by certain types of wave-energy devices. The turbine comprises a bladed rotor, 8, in a casing, 5, with ducts, 3 & 4, positioned to ensure that the rotor rotates in the same direction irrespective of whether the flow is from pressure source 1 to pressure source 2 or from pressure source 2 to pressure source 1. Although only two ducts are shown, the turbine can have one or more ducts connected to the pressure source 1 and one or more ducts connected to pressure source 2. <IMAGE>

Description

SPECIFICATION A turbine for oscillating flows This invention relates to a turbine which is designed to produce power from an oscillating flow of a gas or liquid.
In many situations, such as wave-energy devices, there is an oscillating flow of air or other fluid and there is a need for a turbine which will produce power from this oscillating flow. The rotor of the turbine must continue to rotate in the same direction irrespective of the direction of flow of the working fluid.
According to the present invention, the turbine comprises of a bladed rotor in a casing which has ducts for passing the working fluid into and out of the device. The ducts are positioned such that the rotor always turns in the same direction. The working fluid may be a gas or liquid.
A specific embodiment of the invention will now be described by way of an example, an air turbine, with reference to the accompanying drawings in which: Figure 1 shows a front section view of the turbine, Figure 2 shows a side section view of the turbine.
Referring to the drawings, the turbine comprises two ducts, 3 % 4, a casing, 5, two side plates, 6 % 7 and a bladed rotor, 8, mounted on a shaft 9.
When the pressure at 1 is greater than the pressure at 2, then the air flows through the duct 3 and forms a jet which is deflected by the blades mounted on the rotor, 8, thereby producing a torque on the rotor and delivering power to the shaft 9. The air then passes to duct 4 and leaves the device at the low pressure at 2. In Figure 1, the rotor turns anti-clockwise. When the pressure at 1 is below the pressure at 2, then the air flows through duct 4 and forms a jet which is deflected by the blades mounted on the rotor, thereby producing a torque on the rotor, 8, and delivering power to the shaft 9. In Figure 1, the rotor continues to turn anti-clockwise. The air then passes to duct 3 and leaves the device at the low pressure at 1.
The turbine may have one or more ducts of type 3 connected to the pressure source 1 and one or more ducts of type 4 connected to pressure source 2.
The essential feature of this turbine is that the rotor continues to rotate or turn in the same direction irrespective of whether the pressure at source 1 is above or below the pressure at source 2.
1. This invention is a turbine for oscillating flows comprising a bladed rotor in a casing with two or more ducts positioned to ensure that the rotor turns in the same direction and produces a power output irrespective of the direction of flow of the working fluid through the device.
