Abstract

While at the initial design stage one has to rely on systematic experience, empirical 
methods and experimental model tests to predict ship hydrodynamics performance, it is now 
becoming more and more common to involve CFD methods in order to optimise the body 
lines plan. 
The KCS container ship was designed at the KRISO (Korea Research Institute for Ships 
and Ocean Engineering), now MOERI (Maritime and Ocean Engineering Research Institute), 
that can be used as a benchmark model for CFD predictions. 
The aim of this thesis is to compute with preliminary design tools and CFD instruments 
the hydrodynamic performances (resistance, powering and manoeuvrability) of the KCS 
container ship and to validate some numerical results on the basis of the model resistance tests 
performed both at the small Towing Tank from Dunarea de Jos University of Galati (45 m in 
length) and at the large Towing Tank from MOERI. The goal of the comparison is to evaluate 
the chances that a small basin like the one in Galati has to accurately predict the 
hydrodynamic resistance for this type of ship. 
The preliminary hydrodynamic performances are computed using the hydrodynamic 
modules of AVEVA Initial Design system, on the basis of the main dimensions, hydrostatics 
characteristics and the body lines plan of the KCS container ship. 
Also, the CFD instruments may be used as a predictive tool and the naval architects must 
have confidence that the simulation results are an accurate representation of reality. 
SHIPFLOW code has been applied directly to full scale, in order to study the free surface 
potential flow and viscous flow around the KCS hull, delivering the ship resistance. The 
numerical results have been validated using experimental data bases, including experimental 
tests results obtained at the Towing Tank from Galati University, with a model having 3.502 
m length and at the MOERI Towing Tank, for a KCS model with 7.279 m length. 
The comparison between numerical and experimental results suggests the necessity to 
improve the preliminary design tools and the CFD methods in order to obtain realistic 
prediction of the hydrodynamics performances of the large ships. Also, the small towing tank 
from Galati University can be used in order to predict with satisfactory accuracy the 
resistance for this type of ships'.

Abstract

CFD is an emerging area and is gaining popularity due to the availability of ever-increasing computational power. If used accurately, CFD methods may overcome the limitations of experimental and other numerical methods, in some respects. This Special Issue focuses on Computational Fluid Dynamics (CFD) Simulations of Marine Hydrodynamics with a specific focus on the applications of naval architecture and ocean engineering, and it comprises 24 original articles that advance state-of-the-art CFD applications in marine hydrodynamics and/or review the progress and future directions of research in this field. The published articles cover a wide range of subjects relevant to naval architecture and ocean engineering, including but not limited to; ship resistance and propulsion, seakeeping and maneuverability, hydrodynamics of marine renewable energy devices, validation and verification of computational fluid dynamics (CFD), EFD/CFD combined methods, fouling/coating hydrodynamics.
