In the outer domain, free surface Green's function method is used, where the free surface boundary condition is satisfied automatically. On the control...

... ABSTRACT A study on the characteristics of high-speed ship waves in restricted waterways was conducted numerically and experimentally. The Reynolds-Averaged Navier-Stokes (RANS) equation with two-equation turbulence models were adopted in the calculation. Volume of Fluid (VOF) model was used...

... ABSTRACT In recent busy ports and harbors, their tranquility must be affected with not only storm waves propagated from outside but also harbor waves generated by inside ship navigation. In this study, a new generation method of ship waves is developed and installed to a Boussinesq-type wave...

..., the ship wave has a wash effect on the riverbank and breakwaters, which increases the cost of bank embankments and breakwaters (a part of additional construction cost of the canal). In order to help find the optimal scale of the canal, which balances the ship's navigation performance and the construction...

.... This problem is an essential and nontrivial element of the prediction of ship waves within the Neumann-Michell theory, a practical theory use- ful for routine applications to ship design. A simple analytical relation that explicitly determines the wavenumber of insignificant short waves in terms of the Froude...

... of the moored ship in ship waves are simulated based on Cummins's indirect time domain theory. The comparison between simulated results and experimental results showed that the methods adopted in this paper are feasible. The effects of the velocity of passing ship, water depth and the distance between two ships...

... radiated by sources and sinks distributed over a ship hull surface, the highest waves created by a ship that advances at high speed in calm wa- ter are found well inside the cusps of the Kelvin wake. These highest ship waves are much shorter than the waves at the cusps, and are also significantly shorter...

.... In the Venice Lagoon, due to its the peculiar dynamic, this is not entirely true. It is well known that the bed level tend to deepen and the effect of both wind and ship waves is critical for the environment (Rinaldo, 2001, Zonta et al., 2007). For example, in order to protect the lagoon from boat generated...

... ABSTRACT Recently, floating structures in the sea have been constructed in closed water area such as canals or inner harbors in Japan. When a ship passes through the side of that floating structure in the canal, motion of those structure are affected strongly by ship wave generated by passing...

... (Tunaley, 1999). One more of possible reasons for such a discrepancy are that classical solution considered the ship wake in calm water. But the structure of the ship waves in the presence of external surface wave field can be strongly different from the classical one and possess some conceptually new...

... ABSTRACT This paper deals with the measurement and analytical system of wave direction of ship waves generated by an actual small vessel. Authors proposed the system measuring wave direction of ship waves generated by a real small vessel. The observations of ship waves were carried out...

... ABSTRACT Sometimes, the waves generated by a small vessel traveling freely at high speed in a coastal sea area causes severe sea conditions for marine small floating bodies. Therefore, it is very irr~rtant to research the characteristics of the ship waves by a small vessel and the motions...

... moving on the open sea with zero and nonzero Froude numbers are first studied and results are compared with those obtained by the conventional FDM and by experiments. This method is then applied to cases of a ship advancing in a convergent channel to investigate the ship wave reflection and diffraction...
