Abstract: Transient tests can be reliably used for the diagnosis of pressurized pipe systems. As a matter of fact, the pressure signals acquired during these tests can reveal the presence of anomalies, e.g., leaks, since any ...

Abstract: In this paper, the results of laboratory transient tests concerning the interaction between a pressure wave and an in-line device are discussed. Transients are generated by means of a fast and complete closing of an end ...

Abstract: Eigenfrequency shift in a pipe with a blockage is investigated experimentally. The experimental test rig consists of a reservoir-pipe-valve (RPV) system that contains a single partial blockage. Blockages with different ...

Abstract: Recent studies of measured transient pressure signals showed that eigenfrequencies shift with changes in cross-sectional area of the conduit and used this fact to develop blockage-detection algorithms. However, an understanding ...

Abstract: The relationship between leak outflow from a damaged pipe and flow condition inside the pipe plays a crucial role in pressurized pipe systems management. As an example, this relationship is used in leakage reduction ...

Abstract: In this paper, the reliability of a transient test-based technique as a powerful tool in the management of real supply pipe systems is shown. The pressure signal acquired during the first phase of the single completed test ...

Abstract: A stochastic approach for modeling and analysing the transients due to the users’ water consumptions in a real water distribution system is presented. The analysis is based on field measurements of water consumption at ...
