Abstract: (3161 Views)
In this research, airfoil turbine blade airfoil Darriues vertical axis selected from three airfoils NACA0015, NACA0018 and NACA0021. The maximum ratio of the lift coefficients to the drag coefficient was determined in the Q-Blade software, and finally the airfoil NACA 0015 at speeds of 5 and 10M/s has the maximum value of the lift coefficient to the drag coefficient at an attack angle of 13 degrees equal to 2.58 and an attack angle of 6.5 degrees equal to 15.3. Then airfoil NACA 0015 was selected for numerical analysis and the turbulence method K-ω SST was used for numerical analysis and the results were verified using laboratory results. The wind turbine was designed and developed in CATIA software. Four wind fans were used to create wind power. The instruments used in measuring, testing and fabricating were calibrated. The results showed that the Self-Starting power of the porous blade in the speeds of 3, 4, 5, 7, 8m/s was %35, %33, %31, %37 and %48 less than the direct blade wind turbine, respectively.
