摘要
采用SSTk-ω模型,分别对均匀风和剪切风下1.2 MW水平轴风力机在11.26m/s来流风速下的绕流流场进行三维数值模拟。根据模拟结果分析均匀来流和动态风剪切来流对风力机输出功率的影响以及风剪切对风力机三维流场的气动性能影响。研究结果表明:均匀风下,风力机功率计算值与设计值吻合较好;风力机受到风剪切的影响时,能导致叶片表面的载荷和性能发生变化。
SSTk-ω is applied for an three-dimensional numerical simulation of flow field around a 1.2MW horizontal axis wind turbine with 11.26 m / s flow velocity that in uniform wind and wind shear environment respectively.According to simulation results,the paper analyzes the influence of uniform incoming wind and dynamic wind shear on output power of wind turbine,and the infwence of wind shear on its aerodynamic performance of three dimensional flowflied of wind turbine.It is found that the calculated value of wind turbine power is mostly consistent with the design one in uniform wind environment; The wind shear changes the load and performance of blade surfare while uind turbine sutfers.
