摘要

埋地输气管道泄漏声场产生机理和特性尚不明确，制约着管道泄漏声波检测技术的发展。本文使用计算流体力学（Computational Fluid Dynamic, CFD）与离散元（Discrete Element Method, DEM）耦合方法分析管道泄漏的气固作用，结合宽频噪声源模型和阵列成像技术进行泄漏声场分析和测试。数值模拟结果表明，泄漏高速喷流冲击土壤致使泄漏孔外部形成空洞，并在泄漏孔和空洞内产生四极子声源。土壤阻隔导致流体速度和湍流动能减小，能量由流体传递至土壤颗粒，土壤颗粒运动速度达到了10 m/s。1 MPa管道内压下，泄漏喷流的最大流速超过1000 m/s，由此产生的气动噪声声压级达到了180 dB。相较于其他方向，泄漏孔向上时空洞更大，流场和声场能量更强。声场成像结果证明泄漏孔与声源重合，基于地面阵列的泄漏检测具有可行性。

Abstract

The generation mechanism and characteristics of the acoustic field induced by buried gas pipe leaks are not clear, which restricts the development of acoustic-based pipe leak detection. To address this, a coupling method using computational fluid dynamic (CFD) and discrete element method (DEM) was employed to analyze the fluid-solid interaction of buried pipe leaks. The broadband noise source model and array imaging technique were combined to analyze and test the leak-induced acoustic field. The results of numerical simulation show that the leak-induced high-speed jet scours the soil and generates a cavity out of the leak hole, with the quadrupole acoustic source being generated in the leak hole and soil cavity. Flow speed and turbulence energy were found to be reduced by the block of soil. Energy is transferred from the fluid to the soil particles, and the motion speed of the soil particles reaches 10 m/s. Under the 1-MPa internal pressure of pipe, the maximum flow speed of leak jet exceeds 1000 m/s and the generated aeroacoustics have a sound pressure level of over 180 dB. Comparing with the other directions, when the leak hole was upward the cavity is enlarged and the energy of flow and acoustic fields is enhanced. The imaging of acoustic field verified that the acoustic source is coincided with the leak. Leak detection using ground array is feasible.
