Abstract: A shut-off valve for a turbine of an oscillating water column may include a plurality of guide vanes configured to control a fluid flow into a flow passage defined by the turbine. The plurality of guide vanes may be at least partially disposed within the flow passage and may include a plurality of fixed guide vanes and a plurality of movable guide vanes. The plurality of fixed guide vanes and the plurality of movable guide vanes may be sequentially disposed in an alternating pattern in the flow passage.

Abstract: An oscillating water column (OWC) turbine and method of extracting energy therefrom is provided. The OWC turbine includes a shaft (101) rotatable about a central axis (103), and first and second ports (112, 114) disposed around the central axis. A flow passage (104) extends radially-inward from the ports and extends axially therebetween. Rotor blades (120) are coupled to the shaft, intersect the flow passage, and are offset from the central axis by a first distance. First guide vanes (116) intersect the flow passage and are disposed proximal the first port. The first guide vanes (116) include first and second stators (116a, b), the first stators (116a) being positioned between the first port (112) and the second stators (116b). Second guide vanes (118) intersect the flow passage and are disposed proximal the second port. The first and second guide vanes are offset from the central axis by a second distance that is greater than the first distance.

Abstract: A bi-directional flow impulse type turbine arrangement (120) for use with a bi-directional reversing flow (F, Fl, F2)., and in particular for use with an oscillating water column power plant (110). The turbine arrangement has a rotor (132), and first and second sets of guide vanes (140, 142) located on an opposite axial sides of the rotor for directing the bi-directional reversing flow to and from the rotor. The guide vanes are disposed at a greater radius and radially offset from the rotor blades. The turbine arrangement further comprises first and second annular ducts disposed respectively between the first and second sets of guide vanes and the rotor for directing fluid from the guide vanes to the rotor blades. In addition, the vanes have a profile to maintain a constant flow passage between the vanes over a turning section of the vanes, and the rotor blades of the rotor have a higher turning angle, and producing a non-axial outlet downstream flow. The turbine may also incorporate vanes with a slot and a boundary layer blowing arrangement to re-energise and improve the reverse flow over the vanes.
