Abstract

In this study, numerical simulation and analysis of leakage signal characteristics of gas pipelines with different leakage holes were carried out based on Fluent software. It was found that the differences in leakage holes significantly affect the flow field distribution of the leaking pipeline, which in turn affects the leakage detection results. The leakage hole structures and dynamic characteristics of the model significantly affect the acoustic response, and the model with a ball valve produces a higher sound pressure level. The experimental results provide guidance for the design of piping systems and the detection of leaks, and are of great significance in analysing the differences in flow field and noise generation of different leakage hole models. They provide a scientific basis for the design of piping systems and the detection of leaks.
