| Abstract: | In order to improve the precision of wind turbine performance prediction with CFD at stall conditions,a stall-regulated wind turbine LM19,operating at a high wind speed of 18 m/s, is investigated using a steady 3D Navier-Stokes flow solver with one-equation Spalart-Allmaras turbulence model.Firstly,the method for dealing with high amplitude oscillations of the performance convergence history due to large scale separation is discussed.Then the influences of domain scale and grid number on the numerical resul... |
