Leak Detection of the Pipeline Using Acoustic Emission Technique

Abstract

This paper presents an approach to leak detection of pipeline review in term of theoretical analysis such as acoustics and hydromechanics that should be accompanied by explanation of leakage. The acoustic emission signals during leak from a circular hole of different geometries were studied both analytically and experimentally. The relationships between acoustic parameters and fluid mechanical parameters also were derived analytically. A quadrupole aerodynamic model was applied in the analysis of leak form the circular hole. Computer simulation results demonstrate the effectiveness of the proposed approach. In addition, the leak source location results are also presented by employing the wavelet transform.
