Abstract

This paper introduces an analytical method for predicting the acoustic response of a finite circular cylinder to internal monopole source excitation. The cylindrical shell is attached to rigid end plates. The proposed method accurately predicts the system response, irrespective of whether the internal and external media surrounding the shell are air or water. When the cylinder is filled with a heavy fluid, the cross-coupling between internal acoustical modes and shell structural modes becomes crucial in determining the accurate response both on the shell and inside the cylinder. Similarly, if the cylinder is submerged in a heavy fluid, the cross-coupling between shell modes through modal sound radiation also plays a significant role in determining the shell’s response and the radiated sound field. The accuracy of our method is validated through excellent agreement with calculated results obtained from finite element / boundary element models.
