Dynamics analogous to those of surface ship waves on water of finite depth are noted for the three-dimensional trapped lee wave modes produced by an isolated obstacle in a stratified fluid. This vertical trapping of wave energy is modeled by uniform upstream flow and stratification, bounded above by a rigid lid, and by a semiinfinite fluid of uniform ...

Structures and Mechanisms of Air-Entraining Quasi-Steady Breaking Ship Waves
Journal of Ship Research, 2019The overall objective of this study is to develop a fundamental understanding of the quasi-steady breaking wave regions present in surface ship wakes. Our approach uses direct numerical simulation (DNS) and implicit large eddy simulation. Building on our

This review shows how nonlinear wave generation makes an essential contribution to the near field structure of ship wakes. Many photographs of ship wakes in the laboratory are presented, all of which show evidence of the nonlinear character of the waves at generation.

Journal of Hydrodynamics, 2013
Abstract The bow wave generated by a ship hull that advances at constant speed in calm water is considered. The bow wave only depends on the shape of the ship bow (not on the hull geometry aft of the bow wave). This basic property makes it possible to de- termine the bow waves generated by a canonical family of ship bows defined in terms of ...

An Earth-fixed observer to ship waves
Journal of Fluid MechanicsThis work deals with the linear surface waves generated by a vessel advancing at a constant forward speed. These waves, known as ship waves, appear stationary to an observer on the vessel.

Study of a Container Ship with Breaking Waves at High Froude Number Using URANS and DDES Methods
Journal of Ship Research, 2020The KRISO container ship model is used for numerical simulations to investigate hydrodynamic performance under high speeds. Unsteady Reynolds-Averaged Navier-Stokes (URANS) and delayed detached eddy simulation (DDES) approaches are used to resolve the ...

EFD and CFD Study of Forces, Ship Motions, and Flow Field for KRISO Container Ship Model in Waves
Journal of Ship Research, 2020Ship motion responses and added resistance in waves have been predicted by a wide variety of computational tools. However, validation of the computational flow field still remains a challenge.

Growlers in otherwise open water present a distinct risk to vessels, particularly when waves are present. Waves can hide “small” pieces of hard glacial ice while causing impacts with them to be more intense, or to occur at locations above a ship’s ice belt.
