Numerical Calculations of Ship Induced Waves
Nowadays, various numerical methods are developed to extend computational fluid dynamics in engineering applications. One of the most useful methods in free surface modeling is Boundary Element Method (BEM). BEM is used to model inviscid fluid flow such as flow around ships. BEM solutions employ surface mesh at all of the boundaries. In order to model the linear free surface, BEM can be modifie...
متن کاملEffects of Ship Motion on Ship Maneuvering in Waves
Ship maneuvering performance is typically predicted in calm water conditions. This provides very valuable information at the initial ship design stage. However, since the ship always sails in waves, the maneuvering performance of the ship in seaway may be significantly different from calm water condition. Therefore, if the effect of waves and the corresponding motion responses can be included i...
متن کاملExtreme Waves and Ship Design
Recent research has demonstrated that extreme waves, waves with crest to trough heights of 20 to 30 meters, occur more frequently than previously thought. Also, over the past several decades, a surprising number of large commercial vessels have been lost in incidents involving extreme waves. Many of the victims were bulk carriers. Current design criteria generally consider significant wave heig...
متن کاملShip Underkeel Clearance in Waves
A method is described for combining squat, heel and wave-induced motion calculations into an overall underkeel clearance (UKC) assessment, based on the “dynamic draft” at all the corners of the ship. Particular attention is given to predicting ship motions in shallow water. The effects of resonant roll, wave spreading and extreme motions are discussed. A general UKC assessment is proposed, vali...
متن کاملComposite Scattering of Ship on Sea Surface with Breaking Waves
The composite backscattering of the ship model on sea surface is investigated with the spilling breaking waves and ship bow waves. The spilling breakers are approximately modeled with the wedge-like waves, and the ship bow waves are simulated based on the Kelvin model. With the modified four-path model, each scattering component is evaluated with the high frequency approximation methods for the...
