Time reversal of waves in hydraulics: experimental and theoretical proof with applications

Geolocalization of water-waves origin within water distribution networks using time reversal of first event detection

“…This already permits to back-track the wave origin using a time-reversal method. Time reversal methods, either at the individual pipe level (Grigoropoulos et al, 2021) or at the network one (Shen et al, 2016) have already permit computationaly efficient source identification. This method has been used to develop noisetolerant pipeline defect detection (Wang and Ghidaoui, 2018;Wang and Xie, 2018;Meniconi et al, 2021) in the precise context of water-hammer waves.…”
