Anti-slamming bulbous bow and tunnel stern applications on a novel Deep-V catamaran for improved performance

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2013
While displacement type Deep-V mono hulls have superior seakeeping behaviour at speed, catamarans typically have modest behaviour in rough seas. It is therefore a logical progression to combine the superior seakeeping performance of a displacement type ...

Bulbous bow shape optimization

open access: yes, 2013
The aim of this study is to prove the usefulness of a bulbous bow for a fishing vessel, in terms of drag reduction, using an automated shape optimization procedure including hydrodynamic simulations. A bulbous bow is an appendage that is known to reduce the drag, thanks to its influence on the bow wave system. However, the definition of the geometrical

Analysis of fatigue strength of titanium-steel flange connection bolts in ship

open access: yesZhongguo Jianchuan Yanjiu, 2019
[Objectives] Bolt is usually used in connection for titanium alloy bulbous bow domes of new types of ships and such connection is exposed to bow slamming and wave loading,thus fatigue analysis of titanium-steel connection structure is necessary.[Methods]

Preliminary Bulbous Bow Design Tool Applying K Nearest Neighbours Classification and Regression Model [PDF]

open access: yes, 2021
Designing bulbous bows for ships remains a challenging task.  Their impact on different design attributes as well as their change in performance when operating off their intended design condition renders this as a multidimensional problem.

The sensitivity of ship resistance to wall-adjacent grids and near-wall treatments

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2018
Numerical simulations of turbulent flows around KCS have been performed to study the sensitivity of ship resistance to wall-adjacent grids and disclose the influence of near-wall treatment on the sensitivity of ship resistance.

Analisa CFD Pengaruh Penambahan Appendage pada Lambung Katamaran terhadap Hambatan Viskos

open access: yesJurnal Teknik ITS, 2012
Penambahan tonjolan (appendages) pada lambung kapal sering dimanfaatkan oleh para desainer untuk meningkatkan performa seekeping kapal ketika beroperasi di air, seperti misalnya penggunaan pelat lajur bilga (bilge keel) dan tonjolan haluan (bulbous bow).
