マグナス風車の円柱翼の表面構造と空力特性

(円柱の表面形状の影響)

Cylindrical wings with smooth surface, longitudinal grooves and spiral fins are used to clarify the performance of the magnus wind turbine. Number of revolutions of wind turbine was measured by using a wind tunnel at wind speed of 4~40 m/s and a cylinder rotation at 400~1600 rpm. As the results, it was revealed that a spiral fin has a wind turbine rotation with the lowest wind velocity and a longitudinal groove cylinder has a highest rotation number of wind turbine.
