PCCP Profiling and Tube Wave Analysis of WRE Signal
Acoustic wave propagation due to the breakage or slippage of reinforced wire in water-filled prestressed concrete cylinder pipe (PCCP) attracts interest in non-destructive pipe testing. Current practice of acoustic emission (AE) detection and wire-break related events (WRE) recognition is based on field data analysis. This work deals with the theoretical investigation of WRE signal from generation to propagation through water-filled PCCP.
The COMSOL simulation is based on Navier’s equation of motion. Newton’s law of motion in equilibrium is used to consider the fluid-structure interaction during the propagation. In this paper we verified our simulation results with the theoretical calculated values.
