Abstract
The technical memorandum considers the acoustic radiation from a submerged flooded cylinder. The cylinder has rigid outer walls, identical flexible end-plates, and a flooded interior. The interior and exterior fluids may have different densities and sound speeds, although both fluids are assumed homogeneous. The acoustic field is generated by a pair of radially symmetric, and axially antisymmetric, impulsive pressures applied to the end-plates. The main focus of this report is computation of single low-frequency components of the resulting exterior acoustic field. These components could also serve to model the steady-state response to harmonic forcing. The monochromatic solution technique is based on a set of integral equations, which describe the coupling between the interior and exterior acoustic fields and the motion of the two plates.
