摘要

In order to investigate the characteristics of water supply pipeline sound source, based on the theoretical analysis of the generation mechanism of water supply pipeline leakage sound source. The water supply pipeline leakage flow field and sound field model were established, And after applying Fluent software calculation, the flow field data were imported into the acoustic software: Virtual.Lab. The simulation results under different leakage orifice diameter, pipe pressure and fluid flow velocity were obtained through the model control variables. The results show that: 1. the sound energy of the leakage sound source of the water supply pipeline is mainly concentrated in the infrasound frequency band of 0-10Hz; 2. The larger the leakage orifice diameter, pipeline pressure and fluid flow velocity, the larger the sound pressure value of the leakage sound source.
