These events have been performed by using collect data in transient tests obtained for different pipe system characteristics (two experimental facilities and a real-life system). Current commercial transient solvers cannot accurately predict the head oscillations in pipes with non-elastic rheological pipe-wall behaviour, such as polyethylene PE, whose application in water supply systems has increased during the last years. Experimental procedures are carried out aimed at the collection of data sets of dynamic effects through pressure time variation and flow velocity fields. Pressure transients that naturally occur in pipe systems propagate back and forth in the pipes and carry information about features of the system, such as the presence of a leak, providing a potential tool for leak detection. damping effects, dynamic conditions, leak detection, pipe-wall behaviour, water pipe system This content is only available as a PDF. © IWA Publishing 2006 You do not currently have access to this content.
