Counter-rotating vertical axis wind turbine with deflector and vortex generators

摘要

A high efficiency vertical axis wind turbine (VAWT) comprising two counter-rotating rotors, each comprising a plurality of straight rotor blades. One rotor is placed on a first vertical axis and another rotor is placed on a second vertical axis. The first vertical axis and the second vertical axis are positioned on a support structure extending there between. The support structure, and the first vertical axis of rotation and second vertical axis of rotation, can rotate about an intermediate axis of rotation, which is placed at a midpoint between the first vertical axis of rotation and second vertical axis of rotation. An angled deflector is mounted to the frame at or about the intermediate axis of rotation. During operation, the vertex of the deflector is positioned toward oncoming wind. The deflector comprises two symmetrical deflecting surfaces that extend from the vertex to the rotors. One or more vortex generators are positioned on each deflecting surface.
