This book, Fundamentals of Compressible Flow, describes the funda-
mentals of compressible flow phenomena for engineers and others. This book is
designed to replace the book(s) or instructor’s notes for the compressible flow in
(mostly) undergraduate classes for engineering/science students. It is hoped that
the book could be used as a reference book for people who have at least some
knowledge of the basics of fundamental fluid mechanics, and basic science such
as calculus, physics, etc. It is hoped that the computer program enclosed in the
book will take on a life of its own and develop into an open content or source
project.
The structure of this book is such that many of the chapters could be
usable independently. For example, if you need information about, say, Fanno
flow, you can read just chapter 9. I hope this makes the book easier to use as a
reference manual. However, this manuscript is first and foremost a textbook, and
secondly a reference manual only as a lucky coincidence.
I have tried to describe why the theories are the way they are, rather than
just listing “seven easy steps” for each task. This means that a lot of information
is presented which is not necessary for everyone. These explanations have been
marked as such and can be skipped. 16 Reading everything will, naturally, increase
your understanding of the fundamentals of compressible fluid flow.
This book is written and maintained on a volunteer basis. Like all vol-
unteer work, there is a limit on how much effort I was able to put into the book
and its organization. Moreover, due to the fact that English is my third language
and time limitations, the explanations are not as good as if I had a few years to

15 To the power and glory of the mighty God. This book is only to explain his power.
16 At the present, the book is not well organized. You have to remember that this book is a work in
progress.
