Numerical simulation on the aerofoil aerodynamic performance of wind turbine blade
摘要
Abstract
Four kinds of aerofoil of wind turbine blade which are NACA23012, NACA4412, S809 and S810 were studied by numerical simulation method, and the aerodynamic performance of the static and oscillate aerofoil was analyzed. With the angle of attack becoming larger, the lift coefficient of the static aerofoil first increased and then decreased, however, the drag coefficient continuously increased.lt showed NACA4412 aerofoil had a better low-speed start-up performance. The lift coefficient curve of the oscillate aerofoil was presented a closed hysteresis loop cycle with the angle of attack increased. The hysteresis effect of the S809 aerofoil was most obvious. Based on the simulated data and the experiment data, the reliability of numerical simulation was verified.关键词
