Abstract

The free vibration of a fluid/structure system consisting of a cylindrical blockage
submerged in a liquid enclosed by a cylindrical shell is investigated for the purpose of pipe line
transportation monitoring. The wavenumbers are obtained and the reflection and transmission
characteristics of these waves at the blockage interfaces are investigated theoretically. Reflection
and transmission ratios are obtained in the axisymmetric mode, as functions of frequency. High
order modes play an important role in the near field of the discontinuity and are taken into account.
