縦渦により駆動される円柱翼型風車の動力特性に及ぼす翼長さの影響

抄録

The cylinder blade wind turbine is driven and rotated by that the longitudinal vortex is formed steadily between the cylinder blade and ring-plate placed behind the cylinder blade. In this report, the influence of form factors such as the width of ring-plate and the diameter of the cylinder blade on the blade length for the most effective forming of the longitudinal vortex has been examined. The flanges are attached on a cylinder blade to place the inside and outside of the ring-plate and the effective blade length is controlled by changing their distance. The effective blade length increases as the width of ring-plate increases at a constant diameter of cylinder blade. On the other hand, even if the diameter of cylinder blade is changed, the blade length scarcely changes at a constant width of ring-plate.
