The exact solution for radiation from a cylindrical pipe obtained by using the Wiener}Hopf method has been available for over 50 years. Approximate solutions can be used to simplify the problem, and their accuracy compared with the exact solution. Firstly, the exact solution can be simpli"ed by usin

The prediction of the noise radiated by a fluid-loaded structure generally requires heavy calculations. If the fluid density is "small enough", the structure's response is very close to the in vacuo one. Perturbation techniques account for this particular property: the structural damping, due to the
A discussion of sound propagation in a moving #uid con"ned by cylindrical walls is presented. Based on the continuity equation and the Euler equation, a single &&exact'' ordinary di!erential equation in the acoustic pressure is derived for the case where the medium #ow v (r) depends on the radial co
This work deals with an axisymmetrical shell composed of a cylindrical shell closed by two hemispherical shells made of the same material and with the same thickness. The shell is immersed into a homogeneous perfect #uid extending to in"nity. The "rst part is devoted to the establishment of the equa
