| 中文摘要: |
| 本文在分析突体马蹄涡和湍流脉动压力特性的基础上，在中国船舶科学研究中心03B水筒，试验比较了不同剖面线型的突体模型流动噪声，降噪效果3-sdB．提出了突体剖面低噪声设计的实验依据和具体方法． |
| 英文摘要: |
| 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. |
