摘要
采用大涡模拟方法对风力机翼型全流向绕流进行数值模拟研究。以典型的风力机翼型DU 97-W-300和DU 93-W-210为例,分别开展全流向绕流大涡模拟数值求解,计算得到的全流向翼型气动力与试验值吻合较好,计算精度高于估算方法与RANS方法,表明大涡模拟方法可为叶片的精细设计提供可靠的气动数据。
The flows around DU 97-W-300 and DU 93-W-210 wind turbine airfoils at angle of attack ranging from -180 degree to 180 degree were simulated by the Large Eddy Simulations (LES) method. Compared with the experimental data, the computational results of LES method provide more reliable aerodynamic data than the estimate model and the method based on Reynolds Averaged Navier-Stokes Equations, which shows that the LES method has the superiority in the prediction of aerodynamic data necessary for the structure design and stability analysis of wind turbine blade.
