The ability to obtain flow field predictions of surface ships with Reynolds Averaged Navier-Stokes (RANS) codes has improved tremendously in the last few years. This has been a result of improvements in experience, RANS codes in general, and computer capacity. In particular, the move to parallel processing has been a major catalyst for the recent improvements and a threshold of the usefulness of RANS may well have been crossed. This is particularly significant at a time the U.S. Navy is attempting to move to high-speed ships and more operations in the littorals, both of which are driving ship designs well outside of the traditional experience and experimental data bases. A discussion of where RANS computations may be able to significantly influence the current design and analysis process for surface ships is discussed. Specific areas include: hull flow field and resistance, propulsor inflow, waterjet inlets, bilge keel and appendage alignment, roll motions, maneuvering forces, and scale effects. A number of examples are given for various configurations including: Athena fitted with waterjets, AWJ-21, CG-47, DDG-51, an early DD(X) concept, an aircraft carrier, and Sea Shadow.

Fundamentals of Ship Hydrodynamics: Fluid Mechanics, Ship Resistance and Propulsion Lothar Birk, University of New Orleans, USA Bridging the information gap between fluid mechanics and ship hydrodynamics Fundamentals of Ship Hydrodynamics is designed as a textbook for undergraduate education in ship resistance and propulsion. The book provides connections between basic training in calculus and fluid mechanics and the application of hydrodynamics in daily ship design practice. Based on a foundation in fluid mechanics, the origin, use, and limitations of experimental and computational procedures for resistance and propulsion estimates are explained. The book is subdivided into sixty chapters, providing background material for individual lectures. The unabridged treatment of equations and the extensive use of figures and examples enable students to study details at their own pace. Key features: • Covers the range from basic fluid mechanics to applied ship hydrodynamics. • Subdivided into 60 succinct chapters. • In-depth coverage of material enables self-study. • Around 250 figures and tables. Fundamentals of Ship Hydrodynamics is essential reading for students and staff of naval architecture, ocean engineering, and applied physics. The book is also useful for practicing naval architects and engineers who wish to brush up on the basics, prepare for a licensing exam, or expand their knowledge.

This book addresses some key questions - Did the marine sector drive the developing technologies? Or did it just adopt them? It would appear that the former is the case - as the industry has moved from sail to steam, from steam to internal combustion engines, from wood to steel and to increasing sizes and types of specialist vessels - the pioneers of naval architects and marine engineers have applied the latest technologies, and our global society has benefited.

During the last decade significant progress has been made in the field of ship stability. Yet in spite of the progress made, numerous scientific and practical challenges still exist with regard to the accurate prediction of extreme motion and capsize dynamics for intact and damaged vessels, the probabilistic nature of extreme events, criteria that properly reflect the physics and operational safety of an intact or damaged vessel, and ways to provide relevant information on safe ship handling to ship operators. This book provides a comprehensive review of the above issues through the selection of representative papers presented at the unique series of international workshops and conferences on ship stability held between 2000 and 2009. The editorial committee has selected papers for this book from the following events: STAB 2000 Conference (Launceston, Tasmania), 5th Stability Workshop (Trieste, 2001), 6th Stability Workshop (Long Island, 2002), STAB 2003 Conference (Madrid), 7th Stability Workshop (Shanghai, 2004), 8th Stability Workshop (Istanbul, 2005), STAB 2006 Conference (Rio de Janeiro), 9th Stability Workshop (Hamburg, 2007), 10th Stability Workshop (Daejeon, 2008), and STAB 2009 Conference (St. Petersburg). The papers have been clustered around the following themes: Stability Criteria, Stability of the Intact Ship, Parametric Rolling, Broaching, Nonlinear Dynamics, Roll Damping, Probabilistic Assessment of Ship Capsize, Environmental Modelling, Damaged Ship Stability, CFD Applications, Design for Safety, Naval Vessels, and Accident Investigations.
