Page 29 - 48Fundamentals of Compressible Fluid Mechanics

This book started because I needed an explanation for manufacturing engineers.
Apparently many manufacturing engineers and even some researchers in manu-
facturing engineering were lack of understanding about fluid mechanics in particu-
larly about compressible flow. Therefore, I wrote to myself some notes and I con-
verted one of the note to a chapter in my first book, “Fundamentals Of Die Casting
Design.” Later, I realized that people need down to earth book about compressible
flow and this book was born.
The free/open content of the book was created because the realization
that open content accelerated the creation of books and reaction to the corruption
of the court implementing the copyright law by manufacturing facts and laws. It was
farther extended by the allegation of free market and yet the academic education
cost is sky rocketing without a real reason and real competition. There is no reason
why a text book which cost leas than 10$ to publish/produce will cost about 150
dollars. If a community will pull together, the best books can be created. Anyone
can be part of it. For example, even my 10 years old son, Eliezer made me change
the chapter on isothermal flow. He made me realized that the common approach to
supersonic branch of isothermal as non–existent is the wrong approach. It should
be included because this section provides the explanation and direction on what
13
Fanno flow model will approach if heat transfer is taken into account .
I realized that books in compressible flow are written in a form that is hard
for non fluid mechanic engineer to understand. Therefore, this book is designed
to be in such form that is easy to understand. I wrote notes and asked myself
what materials should be included in such a book so when I provide consultation
to a company, I do not need to explain the fundamentals. Therefore, there are
some chapters in this book which are original materials never published before.
The presentation of some of the chapters is different from other books. The book
13 Still in untyped note form.
