Abstract: With the size of wind turbine getting larger, the impact of wind turbines noise on the environment
cannot be ignored. Therefore, the prediction and control of wind turbine aerodynamic noise should be con-
ducted. A turbine blade with NACA and DU series airfoils was selected as the research baseline. The modified
BPM semi-empirical model was used to calculate aerodynamic noise characteristics of blades. The influence
of blade shape parameters and turbine operating conditions on aerodynamic noise of horizontal wind turbine
blades was studied, through modifying the factors such as airfoil series, chord, wind turbine operating states,
wind shear index, inflow direction, etc. Simulation results showed disciplines of varying of the aerodynamic
noise from different aspects, which provides a reference for the development of high efficiency and low noise
wind turbine blades.
Keywords: Wind turbine blade; Aerodynamic noise; Blade geometric parameters; Wind turbine parameters;
