| 摘 要： | 本文采用CFD软件包FINE~(TM)/Turbo,以两叶片NREL Phase Ⅵ风力机的风轮为对象,进行风轮三维绕流的定常黏性数值分析研究.详细对比了计算结果与实验数据,包括功率、叶片展向五个截面压力系数分布及沿展向载荷系数分布,并分析了三维黏性流场流动细节.结果显示在大部分风速条件下数值模拟可以很好地预估风力机气动性能,在所有计算风速条件下均能够较好地模拟叶片表面的压力分布和展向载荷分布.在失速条件下对根部大分离区的模拟有偏差.

| Abstract: | Numerical investigations of steady and viscous flow around NREL Phase VI wind turbine are carried out with a commercial CFD software FINE~(TM)/Turbo.Compared with the experimental data,including the static pressure at five spanwise sections,blade loading coefficients along spanwise and the aerodynamic power at difierent wind speeds,the numerical results show that the aerodynamic performance in a wind turbine can be well predicted at most of computed wind speeds,with some deviations exist at a position of inboard portion of the blades at a stall wind speed. |
