Rotor for a wave energy converter, wave energy converter and method for operating a wave energy converter

摘要

The invention relates to a Savonius type rotor (100) for a wave energy converter for converting energy from wave motion of a fluid to another form of energy rotatably mounted about a horizontal axis of rotation (110) comprising at least three substantially each Rotation axis (110) radially outward to an outer radius and in the axial direction between two side edges extending, planar wing (101) for coupling to the wave motion, wherein each two adjacent wings (101) of the at least three wings (101) with their closer to the Rotary axis (110) located ends form a flow passage (140) for the fluid, wherein each of the at least three wings (101) in a plane perpendicular to the rotation axis (110) has a cross-sectional profile with a curved course, each point of the cross-sectional profile in polar coordinates in which the axis of rotation (110) defines the pole, indicate lä sst, and wherein the points of the cross-sectional profile with full outer radius and 0.8 times the outer radius with respect to their polar coordinates have an angular difference between 6 ° and 16 °, in particular between 10 ° and 12 °, and such a wave energy converter and a method for Operating such a wave energy converter.
