Vertical Axis Wind Turbine Power Estimation

  1. Sep 22, 2012 #1
    Hello,

    Can some explain to me how to calculate the power coefficient of a vertical axis wind turbine.

    If you explain the steps invloved would be great or any external file location where I could refer.

    I have below information

    1) Lift Coefficient.
    2) Drag Coefficient.
    3) Angle of attack.
    4) Rotational Speed.
    5) Airfoil Dimensions.

    Furthermore, I know how to calculate the tangential force coefficient (Ct) as well. I have tried to calculate the power coefficient, but it gives me a value over 1.0 which is impossible.

    Looking forward to hearing
