Theoretical Results for Utilizing Nozzle Between the Wind-Way and Wind Turbine in Roof of the Buildings - Wind Speed Increase for Wind Turbine to Produce Electricity

Bazgir AS

In order to increase the electrical power of the wind turbines, the velocity of the wind blowing on the wind turbine, is the most important factor that has to increase. In this paper it has been recommended that Contraction Nozzles could be applied between Wind Turbines and wind-way to provide the wind through themselves with more velocity. For all cases analysed in this paper, a three dimensional contraction nozzle with the same length (3 meters) but different input (in which wind blows through it) and output segment areas is considered. In the presented calculations, the inlet mean velocity is considered a constant value of in a windward area. Numerical solutions and CFD results have been the same for increased wind velocity in each Nozzle outlet or wind turbine’s inlet. Furthermore, the electrical power of related wind turbines has been numerically calculated in the presence and absence of the nozzles between wind turbines and wind flow and it shows a dramatic increase in wind turbines power.
