Abstract

The important factor in turbine efficiency is turbine Rotation. The higher the rotor time at different speeds, especially at low speeds, increases the turbine power. In this regard, first, the airfoil NACA0015 was selected and the K-ω SST turbulence method was used for numerical analysis. The validation was performed using experimental results. The Wind Turbine was designed and fabricated by CATIA software. The aluminum sheet used by a series alloy is used to make smooth, porous leaves from simple cards and diamond-shaped leaves, in a porous form with 0. 3 mm thick. The instrument used in measurement, testing and fabrication have been calibrated to compute more precisely and to generate wind flow from the four-fan blower. The results show that the darriues vertical axis Wind Turbine with porous and flat blades has begun to Rotation at the speed of 2. 3 and 3. 9 m/s. At the speed of 2. 5 and 3 m/s, the Rotation of Wind Turbine Porous Blade doubled and at the speed of 4 m/s, its Rotation speed was 3 times higher than the speed of Straight Blade turbine. The Rotation of Wind Turbine Porous Blade in speeds of 4. 5, 5, 5. 5, 6, 6. 5 and 7 m/s were 56. 25 %, 20 %, 22 %, 15 %, 7. 5 %, and 12% higher than the Straight Blade turbine and in speed of 8-10 m/s the Rotation of the Straight Blade turbine and Porous Blade turbine is almost equal.
