This book is a basic textbook of comprehensive thermal science and energy utilization technologies, which is divided into two parts: Engineering Thermodynamics and Heat Transfer. Engineering Thermodynamics mainly introduces the basic concepts and laws of thermodynamics, thermophysical properties of commonly used working medium, analysis of typical thermal processes and cycles and ways to improve the cycle efficiency. Heat Transfer mainly introduces the basic laws of heat conduction, convection and radiation, together with the solving methods and technical measures to control the heat transfer process, and design and check methods for heat exchangers. This book absorbs the experience and advantages of similar textbooks, enriches the discussion of basic concepts and laws, and expands the scope of knowledge of thermal engineering. Whether the readers are students embarking on their academic journey or seasoned engineers seeking to enhance their understanding of thermal phenomena, "Thermal Engineering: Engineering Thermodynamics and Heat Transfer" is an indispensable resource that bridges theory with practice, offering invaluable insights into the complexities of thermal systems and their relevance to modern engineering challenges.
