Abstract: A leakage location in a viscoelastic pipe is estimated by generating a transient wave at a downstream node of the pipe. Liquid pressures at plural locations along the pipe are measured. Measured signals are transformed to frequency response functions (FRFs). The FRF from a sensor closest to the upstream node is used to estimate a FRF of transient discharge at the upstream node. A frequency-dependent wave speed of the transient wave is computed according to geometrical dimensions and viscoelastic coefficients of the pipe via the generalized Kelvin-Voigt model. FRFs of liquid pressures at the locations under a hypothetical no-leakage condition are computed according to the FRF of transient discharge and the frequency-dependent wave speed. By using the matched-field processing (MFP) method, which maximizes the signal-to-noise ratio in detection, the leakage location is estimated from the FRFs of liquid pressures.
