On the effects of soil properties on leak noise propagation in plastic water distribution pipes
(2018-08-04)
In many countries, leaks are located in water distribution pipes by using the cross-correlation of pipe vibration measured either side of a suspected leak. However, in modern plastic pipes this can be problematic due to ...
A stochastic model for the speed of leak noise propagation in plastic water pipes
(2021-06-09)
A good estimate of the speed of leak noise propagation is necessary to pinpoint the location of a leak using acoustic correlators. Models currently exist for this purpose, but they do not consider uncertainties in the pipe ...
On the role of vibro-acoustics in leak detection for plastic water distribution pipes
(2017-01-01)
Leaks have been detected and localized in water distribution in many countries for years, by using the cross-correlation of pipe vibration measured either side of a suspected leak and/or by using listening sticks. However, ...
Estimating the spectrum of leak noise in buried plastic water distribution pipes using acoustic or vibration measurements remote from the leak
(2021-01-15)
An appropriate model of leak noise at source is necessary in analytical and numerical approaches to investigate the characteristics of leak noise measured remotely from the leak in buried water pipes. It is extremely ...
Prediction of leak flow rate in plastic water distribution pipes using vibro-acoustic measurements
(SAGE Publications Ltd, 2018)
© 2017, The Author(s) 2017. Leakage from water distribution systems is a worldwide issue with consequences including loss of revenue, health and environmental concerns. Leaks have typically been found through leak noise ...
Vibration radiation from buried plastic water pipes: an experimental investigation at the ground surface
(Katholieke Univ Leuven, Dept Werktuigkunde, 2012-01-01)
'Mapping the Underworld' is a research initiative that is seeking to address the consequences arising from an inability to consistently locate the buried utility service infrastructure without resorting to extensive ...

Uso de python e conceitos de internet das coisas aplicados à técnicas vibro-acústicas clássicas para detecção de vazamentos
(Universidade Estadual Paulista (Unesp), 2021-04-23)
A escassez de água e a distância entre grandes centros urbanos em relação as áreas com disponibilidade de recursos hídricos são obstáculos que elevam o custo de empresas de distribuição de água e saneamento, bem como impõem ...
Point vibration measurements for the detection of shallow-buried objects
(2012-09-04)
A major UK initiative, entitled 'Mapping the Underworld', is seeking to address the serious social, environmental and economic consequences arising from an inability to locate accurately and comprehensively the buried ...
