Abstract
The time domain response of an infinite fluid-filled pipe to an impulsive line force of various azimuthal distributions is derived, based on the Kennard shell equations fully coupled to the interior acoustic field and computing a double Fourier integration in the wavenumber and frequency domain. the transient radial velocity of the shell is used to compute the coupled pressure field in the fluid and investigate the instantaneous intensity vectors in the fluid field. These vectors, evaluated in the near field of the shell wall at several distances form the input force for increasing time, give insight into the exchange of energy between the structure and the fluid as the various waves propagate through the system.
