Thermodynamics Processes and Applications
This book is intended as a reference work in thermodynamics for practicing engineers and for use as a text by undergraduate engineering students. The goal is to provide rapid access to the fundamental principles of thermodynamics and to provide an abundance of applications to practical problems. Users should have completed two years of an undergraduate program in engineering, physics, applied mathematics, or engineering technology.
The material in this book includes equations, graphs, and illustrative problems that clarify the theory and demonstrate the use of basic relations inengineering analysis and design. Key references are provided at the conclusion of each chapter to serve as a guide to further study.
Additionally, many problems are given, some of which serve as numerical or analytical exercises, while others illustrate the power and utility of thermal system analysis in engineering design. There is sufficient material in Chapters 1-2 and 5-11 for an introductory, one-semester course. A more theoretical course would include Chapters 3 and 4, and a more applied course would extract parts of Chapters 12-14 to supplement material presented in Chapters 8-11.
Although this text shows the relationship of macroscopic thermodynamics to other branches of physics, the science of physics is utilized only to give the reader greater insight into thermodynamic processes. Instead of emphasizing theoretical physics, the book stresses the application of physics to realistic engineering problems.
An ideal gas is used initially to model a gaseous thermodynamic system because it is an uncomplicated, yet often realistic model, and it utilizes the reader’s basic knowledge of physics and chemistry. More realistic models for solid, liquid, and gaseous systems are progressively introduced in parallel with the development of the concepts of work, heat, and the First Law of
Thermodynamics. The abstract property known as entropy and its relation to the Second Law complete the treatment of basic principles. The subsequent material focuses on the use of thermodynamics in a variety of realistic engineering problems.
Thermodynamic problems associated with refrigeration, air conditioning, and the production of electrical power are covered in Chapters 8-14. Chapter 14 treats the special topic of high-speed gas flow, providing the connection between thermodynamics and fluid mechanics. Applications in this chapter are found in aerodynamics, gas turbines, gas compressors, and aircraft and rocket propulsion.
