Numerical study of ship motions and added resistance in regular incident waves of KVLCC2 model

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2017
In this study, the numerical investigation of ship motions and added resistance at constant forward velocity of KVLCC2 model is presented. Finite volume CFD code is used to calculate three dimensional, incompressible, unsteady RANS equations.

NUMERICAL SIMULATIONS OF ADDED RESISTANCE IN REGULAR HEAD WAVES ON A CONTAINER SHIP

open access: yesBrodogradnja, 2019
Although shipping was not included in the final text of the Paris Agreement in 2015, IMO (International Maritime Organization) adopted the EEDI (Energy Efficiency Design Index) and the EEOI (Energy Efficiency Operational Indicator) to control climate ...

Added resistance and seakeeping performance of trimarans in oblique waves [PDF]

open access: yesOcean Engineering, 2020
Trimaran added resistance and seakeeping performance in oblique waves with strong nonlinearity are rarely investigated. This paper presents the numerical investigations on them by applying a hybrid method, called the QaleFOAM. This method can simulate a trimaran moving in a large wave field, considering viscous effects and dealing with violent wave ...

NUMERICAL STUDY ON PROPULSIVE FACTORS IN REGULAR HEAD AND OBLIQUE WAVES

open access: yesBrodogradnja, 2022
This paper applies Reynolds-averaged Navier-Stokes (RANS) method to study propulsion performance in head and oblique waves. Finite volume method (FVM) is employed to discretize the governing equations and SST k-ω model is used for modeling the turbulent ...

Strength determination for band-loaded thin cylinders [PDF]

open access: yes, 2018
Cylindrical shells are often subjected to local inward loads normal to the shell that arise over restricted zones. A simple axisymmetric example is that of the ring-loaded cylinder, in which an inward line load around the circumference causes either ...

Complex Rotating Waves and Long Transients in a Ring-Network of Electrochemical Oscillators with Sparse Random Cross-Connections

open access: yes, 2016
We perform experiments and phase model simulations with a ring network of oscillatory electrochemical reactions to explore the effect of random connections and non-isochronocity of the interactions on the pattern formation.

Application of the Design of Experiments and Computational Fluid Dynamics to Bow Design Improvement

open access: yesJournal of Marine Science and Engineering, 2019
Techniques of the design of experiments (DOE) and computational fluid dynamics (CFD) were applied for improving the bow shape of a tanker hull. Through this, a hull that could reduce the added resistance in waves was derived.

Experimental and Numerical Resistance Analysis for a Cruise Ship W/O Fin Stabilizers

open access: yesJournal of Marine Science and Engineering, 2022
Applying fin stabilizers is an effective solution for ship rolls on waves in a seaway. They generally consist of one or two pairs of retractable fins that are symmetrically mounted to both sides of the ship, effectively reducing the roll motion at low or
