Design of flat vanes vertical axis wind turbine

A B ST R A C T This work designs the rotor wind turbine, which uses more effectively for the wind energy and depends on the acting area of the vanes. The frame design consists of three movable vanes to reduce the negative torque of the frame that rotates contrary to the wind. The wind tunnel is used to measure the power coefficient, torque coefficient and angular velocity as a function of wind velocity. The power coefficient is measured experimentally to be equals to 18% and 21% for three and four frames, respectively. The rotor wind turbine is applicable internationally due to its high efficiency, simple construction, and simple technology.
