Transmission line model for simulation of guided-wave defect signals in piping

A simple transmission line model for analytically simulating the guided-wave signal reflected from a volumetric defect of arbitrary shape in piping is described. In the model, the guided-wave interaction with a defect is treated as the one-dimensional problem of plane wave reflection from a boundary...

Zusammenfassung:A simple transmission line model for analytically simulating the guided-wave signal reflected from a volumetric defect of arbitrary shape in piping is described. In the model, the guided-wave interaction with a defect is treated as the one-dimensional problem of plane wave reflection from a boundary of multilayered media of different acoustic impedances in a transmission line. Results of simulation show good qualitative agreement with experimentally measured signals.
