Abstract
The free vibration of a circular membrane in interaction with a fluid contained
in a cylindrical boundary is analysed. The fluid is compressible and assumed inviscid.
The resulting modal parameters are described by non-dimensionalised frequencies, mode shape coefficients and relative modal energy levels between that of the membrane and the fluid. A simplified “bar” model is introduced as a means of describing the characteristics of membrane/fluid strong interaction between axisymmetric modes of the membrane and axial modes of the fluid column only.
