Abstract: According the design standard of wind turbine and considering the influence of tip loss and lift-drag and other factors, Blade Element Momentum (BEM) theory was used to design the blade on a 2MW pitch-control wind turbine to meet the design requirements. To validate the aerodynamic performance of the designed wind turbine blade, full 3D numerical simulation is conducted. Simulation results show that the static pressure, flow characteristics and turbulence intensity are in accordance with the blade aerodynamic characteristics and meet the design requirements. Comparison of the blade spanwise lift-drag coefficients with the 2D results suggests that full 3D numerical simulation can more accurately reflect the aerodynamic performance.

Key words: fluid power transmission and control, MW wind turbine blade, aerodynamic performance, three-dimensional CFD numerical simulation, circle flow field
