Outline of Final Research Achievements |
In order to solve the problems of manufacturing and social acceptability of wind turbines, which are becoming larger and larger, a multi-rotor system with a cluster of wind turbines was studied. It was found that when wind lens turbines were used as wind turbines, the output performance was increased with increasing the number of wind turbines. It was due to the effect of gap flow between the wind turbines. The result means that a cluster of small lens wind turbines can provide higher power generation capacity than a single large wind turbine, and can flexibly respond to the requirements of aeroelasticity and structural strength.

Academic Significance and Societal Importance of the Research Achievements |
これまで風車で高い発電性能を得るためには、単基(シングル)風車を大型化させる方法がとられてきた。本研究で得られた成果は、レンズ風車を複数集めてクラスタ化することで、流体力学的に相乗効果を生み出して発電能力を高められること、また、その効果は基数が多くなるほど高まることを明らかにしたことである。この方法を採用することで、大型1基よりも、小型のクラスタ風車のほうが高い発電能力が得られる上に、空力弾性、および構造強度面からの要請にも柔軟に対応でき、故障にもロバストなシステムとできる。
