摘　　要：针对单相气体流致噪声问题,以某浮式生产储卸油装置(floating production storage offloading,FPSO)大流量天然气处理装置管路系统的压力安全阀为研究对象,采用非定常大涡模拟(large eddy simulation,LES)和Ffowcs Williams-Hawkings(FW-H)声类比模型对其流动特性和流致噪声特性进行研究,得到了压力安全阀(pressure safety valve,PSV)内流场分布,预测了噪声产生位置及其频谱特性,结论可为压力安全阀和天然气管路系统的前期设计提供理论依据和技术支撑。This paper focused on the problem of flow induced noise caused by single-phase gas.Taking a certain type of pressure safety valve(PSV)of large flow natural gas treatment pipeline in floating production storage offloading(FPSO)emptying pipeline as the research object,unsteady large eddy simulation(LES)and Ffowcs Williams-Hawkings(FW-H)acoustic analogy model were used to study its flow characteristics and flow-induced noise characteristics.The flow field distribution in PSV was obtained,and the noise generation position and its spectral characteristics were predicted.The conclusion can provide theoretical basis and technical support for the early design of PSV and natural gas pipeline system.
