The Behavior of an Experimental Model of Wind Turbine with Vertical Axle with Overlapped Cups at Low Wind Speeds
Keywords:
vertical axis wind turbine (VAWT), airfoil, hemispheric cup, overlap, gap
Abstract
This work is based on an experimental model of vertical axis wind turbine (VAWT), which used a pair of hemispherical blades (cups) with variable overlap. Maintaining the rotation speed to a constant value and in order to meet an important criterion for a current generator fitted to the shaft via a speed multiplier is achieved with a centrifugal mechanism. The experiments conducted in laboratory conditions using experimental model wind tunnel at speeds below 4.5 m/s confirm the validity of the concept.
