The Effective Aerodynamic Forces on the Blade and the Rotor of the Wind Turbine

Zaki Haddad, Naif El-Abboud, Nabil Kichkie


Betz theory presents the output power from the disk of wind turbine but the density of the power on the disk (the density of the forces along the blade) isn't cleared. Designing the profile of a wind turbine blade involves determining the aerodynamics and distribution of the lift forces along the blade. There is new method to calculate the relative velocity depending on knowing values ? Wake rotational speed and ? Blade rotational speed [3], by this method the relative velocity will be known and the lift force will be known theoretically so knowing the efficient lift at particular parts of the blade will help engineers to develop design solutions for improving wind turbine output. This paper studies the distribution of relative velocity and the lift forces along the blade, this values will be calculated depended on several values of the tip speed ratio (TSR) for every situation.
