### Abstract

The vibrational characteristics and the input power flow of the cylindrical shell filled with fluid were studied. Based on Fliigge's shell equations, the sound wave equation for the fluid field and the boundary condition at the fluid-structure interface, the dispersion equation for the fluid-shell coupled system was deduced. By using Fourier transforms, the expression of vibrational power flow from the line circumferential cosine harmonic force was obtained. The wave number of propagation wave and input power flow at different flow velocity were given.
