AbstractNowadays, the ratio of the wind energy is increasing over time in terms of energy requirement. Therefore, a lot of studies have been conducted to improve the performance of wind turbines with different designs for wind turbines. Analyzes of the blade designs are investigated by using numerical programs. In this study, the length of support rods in a vertical axis wind turbine was changed and investigated numerically how the length of the support rods affected the moment coefficient. The blade profile used in the vertical axis wind turbine is NACA 4412 and the number of blades is 3. 120 rpm angular velocity is defined for the turbine and input velocity is 7 m/s in x-direction. According to the results, it was seen that the moment coefficient was the highest when the length of the support rods was 0.4 m. Moreover, there was no linear relationship with between the length of the support point and the aerodynamic performance of the turbine.
