Experimental study of self-starting torque required to operate darriues the vertical axis wind turbine

The The wind turbine converts the kinetic energy of the wind current into the rotational energy of the rotor shaft. The use of vertical axis wind turbines as a source of clean energy production is of great importance. Among the advantages of vertical axis wind turbine over horizontal axis wind turbine are low production cost, lightweight, the efficiency of the installation, and use in residential zones. The darriues blades of vertical axis wind turbines are more in the kind of straight or helical blades. The central difficulty of Darius vertical axis wind turbines is their primary self-starting, which is the basis of this study. They increase self-initiation at low speeds. For this purpose, Darius vertical axis wind turbine was designed and built-in CATIA software. NACA0015 is made for airfoils and the material used for straight and porous blades is plain aluminum sheet and porcelain embossed sheet, both of which are series alloys of aluminum and the equipment used in manufactured and calibrated Manufacturing and calibrating. The result showed that the Ambas blade wind turbine needs less torque to start up to a speed of 9m/s than the vertical blade axis wind turbine.
