Coupled Vibration Analysis of a Fluid-Filled Pipe by Wavenumber Prediction
The stability and vibration of fluid-filled pipes are important in many engineering situations and have been extensively studied. In this paper, coupled fluid–structure analysis is carried on by wavenumber prediction. Pipe equations for axisymmetric wave motion are derived, and two kind of axial waves are studied analytically at low frequencies, i.e., , which is a predominantly fluid-borne wave, and , is predominantly a shell wave. Numerical results are subsequently given to show the definitely influence of the pipe and the fluid.
