摘要:
为研究城市管道泄漏次声波信号的传播规律, 通过COMSOL Multiphysics软件建立非金属管道二维模型, 揭示管道次声波泄漏信号的频谱特性和衰减规律。模拟结果表明:气体管道泄漏次声波信号能量主要分布于1 Hz和17 Hz, 泄漏孔径越大, 管内压力越大, 其能量越趋向于17 Hz, 而液体管道泄漏次声波信号能量主要分布于1 Hz; 管道稳态运行时, 管内次声波信号随传播距离的增加而近似成指数衰减, 管内介质密度越小, 次声波信号衰减越大, 且次声波泄漏信号在介质水中衰减速度较空气中的快; 泄漏孔径大小对次声波信号衰减影响不大。
Abstract:
In order to study the propagation rules of leakage infrasound signals from urban pipelines, COMSOL Multiphysics was used to establish 2D non-metallic pipeline models, and reveal the spectrum characteristics and attenuation characteristics of the infrasound wave signal. The simulation results shows that the energy of the leakage infrasonic signal of the gas pipeline is mainly distributed in 1 Hz and 17 Hz. The larger the leakage aperture, the greater the pressure, and the more its energy tends to be 17 Hz. The energy of the leakage infrasonic signal of liquid pipeline is mainly distributed in 1 Hz. During the steady operation of the pipeline, the infrasonic signal in the pipeline decays exponetially with the increase of propagation distance. The smaller the density of the medium in the pipeline, the greater the attenuation of the infrasound signal, and the attenuation speed of the leakage of infrasound signal in water is faster than that in gas. The size of the leakage aperture has little effect on the attenuation of the infrasonic wave.
