Abstract
In this paper, CFD software is used to simulate the Fluent numerical simulation of the DU300 airfoil trailing edge and the trailing edge of DU300. Using LES turbulence model, calculating the FW-H equation, the noise transformed by FFT transform, and the sound field distribution of the blade aerodynamic noise is obtained, and the variation of the aerodynamic noise of the monitoring points at different locations and the attenuation law are analyzed and compared. After DU300 airfoil blunt trailing edge increasing Bionic trailing edge, the influence of aerodynamic performance of the airfoil is very small, and it has a significant effect on the noise reduction. Which provides a certain reference value for the optimization design of wind turbine airfoil, the sound field distribution of the bionic trailing edge has certain broadband characteristics.
