ABSTRACT

For urban usage of an Archimedes spiral horizontal axis wind turbine, the aerodynamic characteristics including output power, power coefficient, and effect of the angle of attack was investigated using proto-type wind turbine model with Archimedes spiral shape. To provide the aerodynamic performance, the experimental model was consisted with Archimedes spiral wind turbine model, torque meter, powder brake with PWM (Pulse Width Modulation) control basic and RPM sensor. The power coefficient as a function of tip speed ratio with more than 85% of Betz limit can be observed successfully. The Archimedes spiral wind turbine model employed in this study shows the similarity with Modern multiblade turbine type. And the maximum power coefficient as a function of the TSR shows the similar that of Ideal Efficiency of Propeller-type turbine. Through the experiments on the angle of attack change, the fundamental information for the automatic yawing system may be provided.
