摘要：

The aerodynamic performance of the blade is simulated by the software of Fluent under the SST k-ω turbulent model when it is under the rated operating conditions, and make sure that the parameter of blade is reasonable. Then the aerodynamic vortex noise on five sections alone radial blade are simulated with the method combined large eddy simulation(LES)and Lighthill acoustic analogy. The sound source distribution is determined, and sound propagation characteristic is analyzed. The method to reduce the aerodynamic noise is mentioned. The result showed that the trailing edge is the main source, the sound propagation is obviously influenced by wake flow in the near field, while it is not affected in the far field;the influence of the relative wind speed is greater than the angle of attack. © 2017, Editorial Board of Acta Energiae Solaris Sinica.
