Textbook in PDF format

This book is an outgrowth of several years of teaching an undergraduate course on turbomachinery at the University of Portland. It provides an introduction to the subject and is suitable as a single-semester course for seniors and first-year graduate students in disciplines such as mechanical, aerospace, petroleum, and chemical engineering. The prerequisites for the course are one semester in each of thermodynamics and fluid mechanics.
The scope of the book has been defined by two objectives. The first is to provide a unified treatment of the subject of the common forms of a turbomachine while covering the basic fluid mechanics and thermodynamics with a detailed discussion of the governing equations.
The second objective is to apply the material to various machines in sufficient detail so that the underlying performance and design factors can be appreciated. With these objectives in mind, topics such as turbine blade cooling, rotor vibrations, computational fluid dynamics, and analysis of the flow, have been omitted as these are best dealt with in specialized courses at graduate level.
The book starts with dimensional analysis for rotating machinery followed by the basic theory of turbomachines. The remainder of the book is divided into two parts. The first part deals with incompressible flow machines such as hydraulic turbines, pumps, fans, and blowers. The second part deals with compressible flow machines such as gas turbines, compressors, and steam turbines. Several worked examples that provide an illustration of the main points have been included in all chapters. In addition, several example problems are included at the end of each chapter. The text uses both SI and English systems of units.
Throughout the book, the focus has been on the understanding of the basic principles of various types of turbomachines. With this in mind, only rudimentary design aspects are presented. This is partly due to my belief that design is best taught in an industry setting and any design must be preceded by sound theory and analysis
