The book describes currently applied and newly developed advanced numerical methods for wave-induced ship motions and loads. Besides well-established computational methods based on strip theory, panel methods and finite volume methods for unsteady Reynolds-averaged Navier-Stokes equations (URANS), recent advances like a fully nonlinear Rankine panel method, URANS calculations including elastic hull deformations, and an improved method to predict added resistance in waves are explained in detail. Furthermore, statistical methods to assess extreme motions and loads are described both for linear and nonlinear responses in a stationary seaway as well as during long-term ship operations. Results of motions and loads, computed using the various methods, are compared with each other and with results of model experiments. Introductory chapters on fluid dynamics, motions of rigid and elastic ship hulls, numerical methods to compute fluid flows associated with wind waves, and the development and simulation of seaways complement the volume. The book will be of interest to post-graduate students, PhD candidates, as well as engineers in the field of naval architecture, ocean, and marine engineering.

Practical Ship Hydrodynamics provides a comprehensive overview of hydrodynamic experimental and numerical methods for ship resistance and propulsion, maneuvering, seakeeping and vibration. Beginning with an overview of problems and approaches, including the basics of modeling and full scale testing, expert author Volker Bertram introduces the marine applications of computational fluid dynamics and boundary element methods. Expanded and updated, this new edition includes: Otherwise disparate information on the factors affecting ship hydrodynamics, combined to provide one practical, go-to resource. Full coverage of new developments in computational methods and model testing techniques relating to marine design and development. New chapters on hydrodynamic aspects of ship vibrations and hydrodynamic options for fuel efficiency, and increased coverage of simple design estimates of hydrodynamic quantities such as resistance and wake fraction. With a strong focus on essential background for real-life modeling, this book is an ideal reference for practicing naval architects and graduate students.

The majority of current techniques used for predicting ship motions rely on assumptions from the potential flow theory. However, this approach is not ideal, since potential flow theory ignores important effects such as breaking waves, turbulence and viscosity, which are significant in problems involving high Froude numbers, those involving large amplitude motions, shallow water problems and problems involving multi-hull ships. These effects should therefore be included in seakeeping and resistance calculations. Reynolds-Averaged Navier-Stokes (RANS) approaches are excellent alternatives to potential flow theory, as they can directly account for viscous effects in their calculations. Towing tank tests are used widely around the world, giving very accurate results. However, these may be costly and time-consuming. Towing tank experiments are also hampered by a limited availability of suitable facilities. Computational simulations offer a fast, low cost alternative to towing tank experiments. Continued technological advances offer ever-increasing computational power, which can be harnessed for viscous flow simulations to solve the Navier-Stokes equations. Computational Fluid Dynamics (CFD) methods are rapidly gaining popularity for naval architecture, ocean and marine engineering applications. The application of CFD techniques to seakeeping problems allow designers to assess the seakeeping performance of a vessel whilst it is still being designed, enabling any necessary corrective action to be taken before the vessel is actually built. This work mainly aims to perform hydrodynamic analyses of mono- and multi-hull ships, and to develop a CFD-based unsteady RANS numerical model to predict the hydrodynamic performance of these ships. This model will cover seakeeping and resistance calculations in both deep and shallow water regions. Firstly, a detailed literature review of the existing numerical methods which have been developed to solve seakeeping problems of ships is performed. This review also looks in detail at the differences between seakeeping analysis techniques; the reasons for these differences are investigated. Following this, unsteady RANS simulations are performed for various seakeeping and resistance applications. In each specific study, the results obtained using a commercial RANS solver are compared to the results obtained using a potential flow theory code and the available towing tank experiments. Finally, the results drawn from each chapter of this thesis are summarised and discussed, and recommendations are made for future research.

The International Conference on Hydrodynamics is an increasingly important event at which academics, researchers and practitioners can exchange new ideas and their research findings. This volume contains papers from the 2004 conference covering a wide range of subjects within hydrodynamics, including traditional engineering, architectural and mecha

The Twenty-Second Symposium on Naval Hydrodynamics was held in Washington, D.C., from August 9-14, 1998. It coincided with the 100th anniversary of the David Taylor Model Basin. This international symposium was organized jointly by the Office of Naval Research (Mechanics and Energy Conversion S&T Division), the National Research Council (Naval Studies Board), and the Naval Surface Warfare Center, Carderock Division (David Taylor Model Basin). This biennial symposium promotes the technical exchange of naval research developments of common interest to all the countries of the world. The forum encourages both formal and informal discussion of the presented papers, and the occasion provides an opportunity for direct communication between international peers.
