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 the continuous wind direction changes based on the RIAM-COMPACT CFD model that was proposed. 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.
