The numerical simulation of NRELPhase VI wind turbine and TU Delft wind turbine with rich experimental data are carried out. The simulation results of aerodynamic force and wake field are compared with the experimental data. The results show that the calculation method can well simulate the blade aerodynamic force and wake of wind turbine under axial wind and yaw wind conditions, and is a numerical simulation method with high engineering accuracy and computational ability.
