縦渦により駆動される円柱翼風車の動力特性

The performance of a novel wind turbine with a circular cylinder propeller driven by the longitudinal vortex generated near a wake ring plate is carried out. The rotation velocity of the wind turbine with a single circular cylinder blade propeller increases with increasing the wind velocity linearly when it exceeds a certain start wind velocity about 2m/s. It is affected by the normalized gap between the cylinder blade and the ring plate, s/d, and the width of the ring plate W/d. This turbine exhibits high torque at the row rotation velocity. The torque and power coefficients increases with increasing the number of the blades until the ten blades.
