The Behavior of an Experimental Model of Wind Turbine with Vertical Axle with Overlapped Cups at Low Wind Speeds

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.
