The book is mainly descriptive, if you're looking for an insight in the mathematical painful aspect of fluid dynamics, this book is not for you. Anyway, there are few codes, written by the author, you can download. Mainly the boolk talks about the flow about a ship, the ship manouvering and the propeller. Per each argument the main problems are addressed.
At the end of the book there is a part dedicated to the developing of a panel code. Good book, maybe overpriced. The book's approach to resistance and propulsion, seakeeping and manoeuvring is sound and solid, first reviewing standard methods and later introducing most recent available CFD techniques. The author is surely familiar with problems encountered in teaching as this is reflected in the examples and exercises given for each topic.
As a university lecturer working in a Spanish-speaking country I would like to see this book translated. My congratulations to the author.
He did what the book title says: This book is what I would have liked to have earlier for my lectures. In spite of being comprehensive, it gives not only a good overview about the physics and current computational methods of the various fields of ship-related hydrodynamics, but contains also a host of valuable ideas which are not well known, and it concentrates on the important aspects within each field. Many exercises show how to apply the facts and methods to practical problems.
A difficulty relates to viscous flow computations: Here specific methods for naval architecture are hardly required; thus this field is handled superficially only. For all other topics I know of no other book of comparable quality. One person found this helpful 2 people found this helpful.
Quite often, in the field of ship design "practical" means oversimplification of the problem, bounding ship design to a sort of empirical art. This is not the case! This book, lively written with a nice balance between the description of the relevant physics and the rigorous mathematical foundation of the problems, leads the reader to approach ship design by sophisticated, though still feasible, methods.
I think is a wonderful teaching tool! PhD students will find a large number of useful references. Finally, not of minor importance, it can be used by well trained naval architects to get quickly a basic understanding of modern CFD tools, their importance and limits. I found this book really helpful in my research. Especially sections devoted to CFD basic techniques and manoeuring topics provived me very useful information.
In my opinion this reference covers broad range of ship hydrodynamics subjects and is a great source of information not only for researchers but also for naval architecture students and industry engineers engaded in ship hydrodynamics. Web support with source codes and solutions to exercises is an excellent idea. I'm a a mechanical engineer specialized in FE analysis, I know a little of hydrodynamic theory and of applications to ships. I was looking for a book on which I could find practical hydrodynamics, without much theory and practical applications to ships.
This book is exactly what I was looking for.
I suggest it to everybody is doing CFD analysis in every field expecially ships. See all 12 reviews. Most recent customer reviews. Published on June 12, Gernot Pirker dajapana dipdip. Published on July 6, Published on September 26, Pages with related products.

There is no guarantee that the programs are completely debugged and of course neither I nor the publisher will take any responsibility for what happens if you use these programs.
Furthermore, the software is public domain and you may not sell it to third parties. Despite all this, I have worked with most of the software myself without any problems. The website will be updated more often than the book, and there will be a short read. This book is based largely on lectures for German students.
The nucleus of the book was formed by lectures on ship seakeeping and ship manoeuvring, which I have taught for several years with Professor Heinrich Soding. I always felt that we should have a comprehensive textbook that would also cover resistance and propulsion, as ship seakeeping and manoeuvring are both interwoven strongly with the steady base flow. Many colleagues helped with providing material, allowing me to pick the best from their teaching approaches.
A lot of material was written and compiled in a new way, inspired by these sources, but the chapters on ship seakeeping and manoeuvring use extensive existing material. Thanks are due to Seehafen-Verlag Hamburg for permission to reprint text and figures from the Manoeuvring Technical Manual, an excellent book unfortunately no longer in print. Countless colleagues supported the endeavour of writing this book by supplying material, proof-reading, making comments or just discussing engineering or didactic matters. Most of all, Professor Heinrich Soding has supported this book to an extent that he should have been named as co-author, but, typically for him, he declined the offer.
He even refused to allow me to dedicate this book to him. I then dedicate this book to the best mentor I ever had, a role model as a scientist and a man, so much better than I will ever be. Models now in tanks we tow. All of that to Froude we owe. Propeller flows and propeller design can be seen as a subtopic of resistance and propulsion, but it is so important and features special techniques that it is treated as a separate topic in its own right. Morgan and Lin give a good short introduction to the historical development of these techniques to the state of the art in the late s.
The basic approaches can be roughly classified into:. Design engineers need simple and reasonably accurate estimates, e. Common approaches combine a rather simple physical model and regression analysis to determine required coefficients either from one parent ship or from a set of ships. The coefficients may be given in the form of constants, formulae, or curves. Because of the success with model testing, experimental series of hull forms have been developed for varying hull parameters.
Extensive series were tested in the s and the subsequent two decades. The effect of essential hull parameters, e. Because of the expense of model construction and testing, there are no recent comparable series tested of modern hull forms and the traditional ship series must be considered as outdated by now. Although empirical and statistical approaches are still popular in design practice, we will not treat them in detail here, because they are of little relevance to the ship hydrodynamicist.
Ship designers are referred to Schneekluth and Bertram for a review of these empirical approaches. The basic idea of model testing is to experiment with a scale model to extract information that can be scaled transformed to the full-scale ship. Despite continuing research and standardization efforts, a certain degree of empiricism is still necessary, particularly in the model-to-ship correlation which is a method to enhance the prediction accuracy of ship resistance by empirical means. The total resistance can be decomposed in various ways. Unfortunately, this makes various approaches and related aggregated empirical data incompatible.
Although there has been little change in the basic methodology of ship resistance since the days of Froude , various aspects of the techniques have progressed. We now understand better the flow around three-dimensional, appended ships, especially the boundary layer effects.
Also non-intrusive experimental techniques like laser-Doppler velocimetry LDV allow the measurement of the velocity field in the ship wake to improve propeller design. Another more recent experimental technique is wave pattern analysis to determine the wave-making resistance. In propulsion tests, measurements include towing speed and propeller quantities such as thrust, torque, and rpm.
Normally, open-water tests on the propeller alone are run to aid the analysis process as certain coefficients are necessary for the propeller design. Strictly, open-water tests are not essential for power prediction alone.
Practical ship hydrodynamics. 1. Ships – Hydrodynamics. I. Title. Library of Congress Cataloguing in Publication Data. Bertram, Volker. Practical ship. Practical Ship Hydrodynamics, Second Edition, introduces the reader to modern ship hydrodynamics. It describes experimental and numerical methods for ship.
Propulsion tests determine important input parameters for the actual detailed propeller design, e. The wake distribution, also needed for propeller design, is measured behind the ship model using pitot tubes or laser-Doppler velocimetry LDV. For propeller design, measured nominal wakes for the ship without propeller for the model must be transformed to effective wakes for the ship with working propeller for the full-scale ship.
While semi-empirical methods for this transformation work apparently well for most hull forms, for those with considerable flow separation at the stern, i. To some extent, computational fluid dynamics can help here in estimating the scale effects.
AmazonGlobal Ship Orders Internationally. Don't have an account? This book is organized to support such a strategy in teaching. As I could not find such a book, I wrote two chapters intended to support me in my teaching and to be of use for many colleagues. Practical ship hydrodynamics, second edition Author: PhD students will find a large number of useful references.
Although the procedures for predicting full-scale resistance from model tests are well accepted, full-scale data available for validation purposes are extremely limited and difficult to obtain. The powering performance of a ship is validated by actual ship trials, ideally conducted in calm seas. The parameters usually measured are torque, rpm, and speed. Thrust is measured only as a special requirement because of the difficulty and extra expense involved in obtaining accurate thrust data. Whenever possible and appropriate, corrections are made for the effects of waves, current, wind, and shallow water.
