As a particular instance of the complete acoustic radiation problem for an underwater structure, structure-borne noise radiated from a combined submarine-propeller system under self-propulsion condition is investigated. The analysis procedure applies a set of numerical methods to capture different aspects of the problem: unsteady computational flui...
The radiated sound from an underwater structure is primarily due to the flow about the body and vibrations of the body, whether the exciting mechanism is the propulsion system, external flow, or any mechanical component. The current study covers a particular instance of the complete acoustic radiation problem that the structure-borne noise radiated...
The interaction with axial flow can significantly alter the mechanical behavior of plates in qualitative and quantitative terms. A numerical method is presented for the dynamic stability analysis of plates subjected to uniform axial flow, which can serve as a general analysis tool for the positively supported plates within linear theory. The plate...
The Fourier–Kochin theory—an indirect solution approach for the boundary integral representations of free-surface flows that rely on free-surface Green function—is investigated by considering effective computation and reliable prediction. The present study addresses wave–body interaction with zero forward speed by adopting a higher-order approximat...
The ability to perform covert operations is perhaps the most essential feature of submarines and consideration of the noise of submarine structures at the design phase is vital. In this study, the structure-borne acoustic radiation from a submarine due to propeller excitation is numerically predicted by applying a combined finite element/boundary e...
A finite element-boundary element solution method is proposed for the hydroelastic analysis of fluid-filled containers. The dynamics of the elastic container is studied by adopting a shell based finite element procedure. The fluid-structure interaction is considered through the boundary element solution of the potential problem, associated with the...
