内容記述 | In this study, the relationship between the periodic noise and the aerodynamic noise source of a wind turbine is discussed. The aerodynamic characteristics and the noise of the actual wind turbine were measured by wind tunnel; the flow around the impeller immersed in the uniform flow was solved by numerical simulation. In the observed wind turbine, when the mainstream velocity was 7.4 m/s or more, the power coefficient became the maximum at the tip speed ratio 8. When the mainstream velocity became fast in the driving condition of the maximum power point, the aerodynamic noise became large due to the periodical noise in the vicinity of the 1000 Hz and the broadband noise in the high frequency domain. The noise sources were concentrated at the leading edge and the trailing edge on the suction surface side. We indicated that the pressure fluctuation of the leading edge was the noise source of the periodical noise. | |||||
