| 在分析阀门泄漏流噪声机理的基础上，采用计算流体仿真软件CFD，对船用核动力装置边界电磁阀内漏的流场和声场进行稳态和非稳态模拟，获得电磁阀内漏的流场和声场分布规律，并研究流体介质、工作压力、空化效应等因素对电磁阀内漏流声场的影响。研究表明，阀门工作压力、阀门流体种类以及阀门空化等因素与阀门内漏的流声场直接相关。研究对于船用核动力装置边界电磁阀泄漏流噪声特征，对于电磁阀泄漏的智能检测具有重要的借鉴价值，对于保障船用核动力装置系统的运行安全具有重要的参考价值。 |

| On the basis of analyzing the noise mechanism of valve leakage flow, CFD fluid simulation software is used to simulate the flow field and sound field of the boundary solenoid valve leakage in marine nuclear power plant. The distributions of the flow field and sound field of the solenoid valve leakage are obtained. In this paper, the noise characteristics of the boundary solenoid valve leakage flow in marine nuclear power plant are studied, which has very important reference value for intelligent detection of solenoid valve leakage and for ensuring the operation safety of marine nuclear power plant. |
