Outline of Final Research Achievements

It is highly important in Japan to choose a good site for wind turbines, because the spatial distribution of wind speed is quite complicated over steep complex terrain. We have been developing the unsteady numerical model called the RIAM-COMPACT (Research Institute for Applied Mechanics, Kyushu University, COMputational Prediction of Airflow over Complex Terrain). The RIAM-COMPACT is based on the LES (Large-Eddy Simulation). In the present paper, the reproduction method of airflows over steep complex terrain using RIAM-COMPACT CFD model. In addition, we carried out the large-eddy simulation (LES) of the wake generated behind the wind lens turbine (WLT) under optimal tip speed ratio.

Academic Significance and Societal Importance of the Research Achievements

一連の研究成果に基づいて、地形性乱流が大型風車のブレードに与える2種類の新しい定量化指標を提案することに成功しました。この指標を有効に活用することで、風車の「重大事故」を未然に防ぎ、洋上および陸上の大規模風力発電の適切な普及・拡大に大きく貢献することが期待されます。
