Abstract:

The importance of wind energy is increased nowadays in many countries according to intensive electric power demand. Most of the wind turbine designs are conducted at large scale to build farms of power plants. These types are high cost as initial and installation cost. This work is concerned with a new type of Vertical Axis Wind Turbine (VAWT), which is provided with a nozzle. The nozzle is used to duplicate the wind speed in the region which has speed not more than 3 m/s. Moreover, this design is promising in the zones of wind speed less than 4 m/s to be a stand-alone unit for electric generation. The study is performed numerically to survey the influence of this nozzle on the performance and power coefficient of the Drag Vertical Axis Wind Turbine (DVAWT). This type of electric power generation is intended for rural and domestic application. The results indicated that the new design increases the power coefficient by 1.5% compared with the conventional Drag turbine.
