Title: Experimental and Numerical Analysis of Vertical Axis Wind Turbine
Abstract: The Vertical Axis Wind Turbine (VAWT) is effective energy harnessing device in comparison with Horizontal Axis Wind Turbines (HAWT). The focus of the present study is to obtain a rotor blade shape which gives a high power at minimum wind velocity, minimum starting torque, and minimum cut in wind speed. Simulation of the model uses the different wind speeds to determine performance of the wind turbine. A 1200 mm high and 1000 mm swing diameter turbine includes eight blades. An experimental study is carried out for two different blade shapes viz. U shaped blade and the Fan type blade. Experimental results are presented for different air flow velocities in terms of Revolutions per minute (RPM) of rotor, force exerted, and torque required to attain a specific rotor speed. The experimental results reveal that fan type blade gives better performance than U type blade. Power characteristics are also studied for the Fan type blade rotor. The numerical study confirms the experimental results for fan type blade rotor. FAN type blades are analyzed for the different bend angles from 130° to 140°.
