Webinar – Acoustic wave propagation in water pipes, Yicheng Yu (University of Sheffield)
This talk is an introduction to acoustic wave propagation in water pipes. Leakage localization using acoustic methods in water pipes requires the knowledge of wave propagation. Dispersion of acoustic waves inside a water pipe is coupled with the structural vibration of the pipe wall. In addition, the surrounding media (e.g. soil/sand) can affect the wave propagation. This talk will introduce how the properties of the pipe wall and the surrounding media can affect the acoustic wave attenuation.
Speaker
Dr. Yicheng Yu obtained his PhD under the supervision of Prof. Carl Hopkins in the Acoustics Research Unit at the University of Liverpool. His research was on structure-borne sound prediction for buildings and vehicles. He is currently a postdoctoral research associate at the University of Sheffield working on acoustic sensing for robotic platforms to detect defects in pipes (such as blockages or leakages) and monitor pipe conditions.
