摘要
先采用叶素理论对垂直轴风力机叶片受力进行静态的分析,然后采用多流管理论计算出叶尖速比与功率的关系曲线,最后采用滑移网格技术对风力机进行了数值模拟,得到的功率与用多流管理论计算的结果吻合较好.
Firstly, blade element theory is used to analysis static force on vertical axis wind turbine blade. Then multiple streamtubes theory is applied to calculate power curve varying with tip speed ratio. Finally unsteady flow simulation is completed using sliding mesh technique. The simulation prediction of power agrees well with multiple streamtubes result.
