Abstract:

A Vertical-Axis Double-Ducted Vortex-Diffuser-Augmented Wind Turbine comprises an apparatus further comprising a large, hollow, cylindrical tower with external fixed, wind concentrating cowlings and internal hinged, wind inlet vanes. The cowlings are large curved sections that extend outward from the cylindrical tower and perform two functions: 1) capture the wind, entraining it into a tower's core on an upwind side of the tower; and 2) shade a downwind side of the cylindrical tower from the wind, creating a negative pressure on downwind inlet vanes. The inlet vanes extend into the tower's cylindrical core, automatically opening to allow the wind to enter on the upwind side of the tower and automatically close on the downwind side of the cylindrical tower. By working together the external cowlings and internal inlet vanes enable the cylindrical tower to capture and entrain the wind stream into a contained tornado-like vortex.
