摘要:针对船用 PN10DN32 三通调节阀噪声声压频谱、声指向性等声学特性规律不明确,噪声声压级是否满
足使用要求的问题,基于流 -固耦合理论,同时考虑流 -固耦合面及流体域内的脉动声学激励源,开展阀门噪声
数值模拟研究。分别对三通调节阀在 80% 及 60% 开度阀外 1 m 处的噪声进行数值模拟,分析研究噪声声压频
谱特性及声指向性规律。结果表明:80% 及 60% 开度下的噪声声压级分别为 49.14 dB(A)、50.79 dB(A),均小
于 60 dB(A) 的噪声限制,满足使用要求。该文为船用三通调节阀噪声数值模拟提供了理论及方法参考。

Abstract: Aiming at the problem that the acoustic characteristics of Marine PN10DN32 three-way regulating
valve noise spectrum and acoustic directivity are not clear, and whether the sound pressure level of noise meets
the requirements of use, based on the theory of fluid-structure interaction, considering the fluid-structure
interaction surface and the pulsating acoustic excitation source in the fluid domain, the numerical simulation
of valve noise is carried out. The noise at 1 m outside the 80% and 60% opening of the three-way regulating
valve was numerically simulated, and the characteristics of noise sound pressure spectrum and the law of sound
directivity were analyzed. The results show that the sound pressure levels of noise at 80% and 60% opening are
49.14 dB(A) and 50.79 dB(A) respectively, which are both lower than the noise limit of 60 dB(A) and meet the
requirements of operation. It provides theoretical and methodological reference for the numerical simulation of
Marine three-way regulating valve noise.
