Abstract: Fluid flow energy conversion systems employing aerodynamic flow-separation vortex generation for focusing the kinetic energy of flow in the working area of the turbine are disclosed herein in the context of wind power plants. As a consequence of this augmentation, fluid velocity acting on the rotor is increased by a substantial amount over the free stream velocity, resulting in substantial increases in power output for a given turbine configuration. The illustrative embodiments include simple flow separation, vortex augmenting surfaces, such as those found in delta planforms which in this context generate vortices and therefore function as aerodynamic "lenses"; these surfaces are oriented to the wind turbine so that generated vortices are directed at the turbine blades. The latter are configured to be driven by the vortex and drive in turn electrical or other power generating devices or machines.

Abstract: A fluid flow energy conversion system is disclosed which employs a pair of vortex generators to focus the broad diffuse flow intercepted by each planform into concentrated vortices of higher energy density; turbines are oriented in the vortices to convert the vortex energy into mechanical energy to thus provide power output substantially higher than otherwise achievable by the turbines alone; the illustrative vortex generators are delta planforms deployed in mirror symmetric fashion with their apices adjacent to define the apex of a horizontal "V" configuration such that the apex points into the wind, the plane of symmetry aligns with the wind direction, and the angle of the "V" provides the required angle of attack for each planform relative to the wind axis. A three point mounting system employing a pivot near the apex and wheels adjacent the trailing edge, provides the required azimuthal mobility.
