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

Turbine with radial inlet and outlet and multi-element guide vanes for oscillating flows

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.
