Commercial ships and ocean vehicles could contribute significantly to underwater noise
propagating in the marine environment, and propellers are considered to be a main source …

A high-precision numerical sound field is the basis of underwater target detection,
positioning and communication. A line source in a plane is a common type of sound source …

We perform a scaling analysis of the terms composing the Ffowcs-Williams and Hawkings
(FWH) equation, which rules the propagation of noise generated by a rigid body in motion …

Spectral methods are a new and niche numerical discretization method with the main
characteristic of high accuracy. Spectral methods have been applied in many fields of …

Biomimetic flapping-foil thrusters can operate efficiently while offering desirable levels of
thrust required for the propulsion of a small vessel or an Autonomous Underwater Vehicle …

Modeling acoustic propagation accurately is vital to numerous oceanic applications.
However, physics-based acoustic propagation models require accurate prior environmental …

In this paper, a stepwise coupled-mode model with the use of the direct global matrix
approach is proposed. This method is capable of handling two-dimensional problems with …

The coupled-mode model developed by Belibassakis and Athanassoulis (J Fluid Mech 531:
221–249, 2005) is extended and applied to the hydroelastic analysis of three-dimensional …

Finite-element models (FEMs) of ocean acoustic waveguides are capable of predicting the
full wave solution including the effect of inhomogeneities and interfaces. However the …

A new coupled-mode system of horizontal equations is presented for the hydroelastic
analysis of large floating bodies or ice sheets of general, finite thickness, lying over variable …
