2531 風車後流の三次元数値シミュレーション及びそのモデル化に関する検討(S47-5 自然の流体エネルギー利用技術(風車3),S47 自然の流体エネルギー利用技術)  [in Japanese] 2531 Investigation of 3-D numerical simulation and modeling of wind turbine wakes  [in Japanese]

In offshore wind farm, when wind turbines are placed closely each other, a wind turbine is strongly affected by the wake of others. For the wake, a velocity deficit, a fluctuation of output of power, and an increase of fatigue of wind turbine are caused. Hence, a design tool of wind turbine with wake effects is needed. The aim of this research is to obtain a basic study of three-dimensional wake simulation near a wind turbine to make an effective wake model for design. The object of this simulation is wind turbine blade which is experimented by National Renewable Energy Laboratory (NREL). The flow field is calculated with a Detached-Eddy-Simulation (DES).
