recommendations! Published in 2019 at "Engineering Failure Analysis"

DOI: 10.1016/j.engfailanal.2019.04.053

Abstract: Abstract Natural or hydrogen gas is a vital energy carrier, which can serve as an energy source and is extremely vulnerable to leakages from pipeline transportation systems. Although the safety of natural gas pipelines has… read more here.

DOI: 10.1016/j.jprocont.2017.03.015

Abstract: This paper presents a method for leak localization in water distribution networks (WDNs) based on Bayesian classifiers. Probability density functions for pressure residuals are calibrated off-line for all the possible leak scenarios by using a… read more here.

DOI: 10.1016/j.ymssp.2019.02.004

Abstract: Abstract This paper applies the matched-field processing (MFP) method to leakage localization in a viscoelastic pipe. The viscoelasticity of pipe wall is included in the governing equations of transient wave via the generalized Kelvin-Voigt model… read more here.

DOI: 10.1016/j.ymssp.2021.107994

Abstract: Abstract Pipelines are widely used in the transportation of water, oil, gas, etc. Leakage in pipelines leads to a great waste of natural resources and sometimes constitutes a public health risk. Due to its wave-like… read more here.

recommendations! Published in 2022 at "IEEE Transactions on Instrumentation and Measurement"

DOI: 10.1109/tim.2022.3169526

Abstract: Acoustic waves induced by leakage attenuate as they propagate in the piping system. Difficulties are generally encountered in leak localization in plastic pipes since these waves are heavily attenuated than in metallic pipes. This study… read more here.
