The aerodynamic characteristics and surface structure of the cylinder wings of the magnus wind turbine

(effect of surface shape of the cylinder)

Abstract

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.
