Water hammer or flow transients occur due to a sudden variation (over time) in flow
properties that can lead to pipe system failure or damage. In addition, research on wave …

Water-hammer waves propagation is an important phenomenon arising in numerous
applications. It is also a long-standing topic in the fields of mechanics, mechanical …

This paper concerns the use of Transient Test‐Based Techniques (TTBTs) for fault detection
in a long transmission main. It reports the results of two series of transient tests executed in a …

Small leaks in buried water distribution pipelines typically remain undetected indefinitely
because the impact small leaks have on the overall system pressure is imperceptible. This …

Fluid–structure interaction (FSI) due to water hammer in a pipeline which has viscoelastic
wall behaviour is studied. Appropriate governing equations are derived and numerically …

In this paper, criteria for the optimal and market-oriented design of the Smart-Portable
Pressure Wave Maker (S-PPWM) device are presented. The outlined criteria are based on …

In view of scarcity of both experimental data and numerical models concerning transient
behavior of cross-section area changes in pressurized liquid flow, the paper presents …

To date, the use of matched-field processing (MFP) for leak detection in pipes has been
limited to cases where the mismatch between data and model is assumed to be random and …

A mathematical model of the problem of nonlinear oscillations of a viscoelastic pipeline
conveying fluid is developed in the paper. The Boltzmann–Volterra integral model with …

Numerical methods generally need analytical solutions as test cases and validations in
simplified problems. This work provides Laplace-domain explicit analytic solutions for fluid …
