### Abstract

In this paper, the input power flow from a cosine harmonic circumferential line force into an infinite cylindrical fluid-filled shell with periodic stiffeners is studied. The stiffeners are idealized as line attachments capable of exerting line forces which relate to the stiffeners and the shell. The motion of the shell and the pressure field in the contained fluid are described by the Flügge thin shell theory and the Helmholt equation respectively. A periodic structure theory, space-harmonic analysis, is used to investigate this fluid-filled periodic structure. The concept of the vibrational power flow is introduced and the influence of the parameters of the stiffeners upon the results is also dscussed.
