CFD simulation of ship turning motion in waves
Zhongguo Jianchuan Yanjiu, 2019 [Objectives] The ship turning motion can reflect the steerability of the ship during navigation and is closely related to the ship navigation safety.[Methods] In this paper, the direct numerical simulation of the free turning motion of the standard ship ...

An experimental study of unsteady hydrodynamics of a single scull [PDF]
, 2011 The effect of hull dynamics on the hydrodynamic performance of a single scull is investigated via a combination of field trials and tank tests. The location of laminar-turbulent transition in unsteady flow is explored via several series of hot-film ...

Development Of A Semi-Swath Craft For Malaysian Waters [PDF]
, 2006 Small Waterplane Area Twin Hull (SWATH) and Catamaran vessels are known to have more stable platform as compared to mono-hulls. A further advantage of SWATH as compared to Catamaran is its smaller waterplane area that provides better seakeeping ...

Ship Control in Manoeuvring Situations with Fuzzy Logic Controllers [PDF]
TransNav, 2008 In this paper, the ship control regulator in manoeuvring situation is presented. It consists of three fuzzy logic controllers. Each controller controls one of motions: turning, transverse and longitude motion of a ship.

CFD simulations of vertical ship motions in shallow water [PDF]
, 2016 The seakeeping behaviour of a vessel in shallow water differs significantly from its behaviour in deep water. In shallow water, a vessel’s motion responses to incident waves will be affected by hydrodynamic effects caused by the presence of a finite ...
