Hydrodynamic Forces and Wake Distribution of Various Ship Shapes Calculated Using a Reynolds Stress Model

open access: yesJournal of Marine Science and Engineering, 2022
The Reynolds-averaged Navier–Stokes (RANS)-based computational fluid dynamics (CFD) calculation using a two-equation turbulence model, such as the k–omega shear-stress transport (SST) model, is a mainstream method with sufficient accuracy for the ...

Numerical calculation and mechanical mechanism analysis of ship parametric rolling

open access: yesZhongguo Jianchuan Yanjiu, 2020
[Objective] The parametric rolling is a special instability phenomenon of ship in the wave. The current research proves that the change of the stability parameter when the wave passes through the hull is the reason for the rolling motion of the hull,but ...

Ships and Shipping [PDF]

open access: yesNature, 1905
A VERY excellent little volume and a most handy addition to any shipping office. The naval information makes it also a very useful book to naval officers. One slight improvement would be useful—port-to-port distances round the coast of Great Britain and Europe; for example, London to Plymouth. Ships and Shipping. By Commander R. Dowling. With a preface
