Nowadays, 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.
