Abstract

The use of acoustic finite element modal analysis for simulating and identifying blockage in a pipe network is presented in this paper. The analysis commences with a straight fluid-filled pipe without any flaw. The natural frequencies of the acoustic modes of the fluid in the pipe are computed. Blockages of different magnitudes are introduced at different locations along the length of the pipe. The corresponding natural frequencies of the acoustic modes of the fluid in the pipe are again computed by finite element technique. From these results, the modal characteristics of partially blocked pipes are established and compared with simulation results of defect-free fluid-filled pipes in order to ascertain the defect location and sizes.
