Preface<br />

The first five chapters give an introduction to ship hydrodynamics, which is<br />

in my opinion suitable for teaching at a senior undergraduate level or even at<br />

a postgraduate level. It is thus also suitable for engineers working in industry.<br />

The book assumes that the reader has a solid knowledge of general fluid<br />

dynamics. In teaching, general fluid dynamics and specific ship hydrodynamics<br />

are often mixed but I believe that universities should first teach a course<br />

in general fluid dynamics which should be mandatory to most engineering<br />

students. There are many good textbooks on the market for this purpose. Naval<br />

architects should then concentrate on the particular aspects of their field and<br />

cover material more suited to their needs. This book is organized to support<br />

such a strategy in teaching.<br />

The first chapter is an introduction to computational fluid dynamics, and<br />

Chapters 2 to 5 cover the four main areas of propeller flows, resistance and<br />

propulsion, ship seakeeping and manoeuvring. It is recommended that this<br />

sequence be followed in teaching. The first five chapters try to find a suitable<br />

balance for practical engineers between facts and minimizing formula work.<br />

However, there are still formulae. These are intended to help those tasked<br />

with computations or programming. Readers with a practical interest may<br />

simply skip these passages. The final two chapters involve more extensive<br />

formula work and are more specialized. They may be reserved for graduate and<br />

post-graduate teaching and will help understanding and developing boundary<br />

element codes. Field methods are not covered in depth here, as my colleague<br />

Milovan Peric has already co-authored an excellent book on this particular<br />

topic. I tried in vain to find a similar suitable textbook for boundary element<br />

methods which would be both easy to understand and address the typical<br />

problems encountered in ship flows. As I could not find such a book, I wrote<br />

two chapters intended to support me in my teaching and to be of use for many<br />

colleagues.<br />

The book is supplemented by some public domain software written<br />

in Fortran which is available for downloading in source code on<br />

www.bh.com/companions/0750648511. The software consists of small<br />

programs or subroutines which may help in developing own codes. Some of the<br />

programs have been written by myself, some by Professor Söding, and some<br />

by colleagues. Feel free to download the software, but there is no additional<br />

documentation available except for the in-program comments. I will not answer<br />

questions about the software, but you can comment on which programs you<br />
