| Abstract: | In this paper,the experiment on the flow noise from appendage models, pro-files of which are different, is carried out in the CSSRC 03B water tunnel,based on theanalysis of characteristics for horseshoe vortex and turbulent fluctuation pressure.Themethod of designing the low noise appendage is provided, by which the flow noise can bereduced by 3-5dB. |
