Introduction to Thermodynamics and Heat Transfer pdf

Introduction to Thermodynamics and Heat Transfer – Introduction to Thermodynamics and Heat Transfer provides balanced coverage of the basic concepts of thermodynamics and heat transfer. Together with the clear and numerous illustrations, student-friendly writing style, and manageable math, this is an ideal text for an introductory thermal science course for non-mechanical engineering majors.

Continuing in the tradition of “Cengel/Boles: Thermodynamics,” this lavishly illustrated text presents the key topics in thermodynamics and heat transfer, in a highly accessible student-friendly fashion.The flexibly organized text can accommodate courses that spend anywhere from 1/3rd to 2/3rds or more of class time on thermodynamics and the rest on key heat transfer topics. The intuitive approach is supported by a wealth of physical explanations and analogies that draw parallels between the subject and the students’ everyday experiences. Many of the 150 thoroughly worked out examples and almost 2,000 real-world problems, highlight applications from civil and electrical engineering.Over 1,000 illustrations help students visualize concepts. This approach and contents make this text an ideal resource for introduction to thermodynamics and/or thermal science courses intended for non-mechanical engineering majors.

Preface

This text is an abbreviated version of standard thermodynamics and heat transfer texts, covering topics that the engineering students are most likely to need in their professional lives. The thermodynamics portion of this text is based on the text Thermodynamics: An Engineering Approach by Y. A. Çengel and M. A. Boles, and the heat transfer portion is based on Heat and Mass Transfer: A Practical Approach by Y. A. Çengel, both published by McGraw-Hill. Most chapters are practically independent of each other and can be covered in any order. The text is well-suited for curricula that have a common introductory course on thermodynamics and heat transfer. Instructors who desire to incorporate some coverage of fluid mechanics in their courses may wish to use the textbook Fundamentals of Thermal-Fluid Sciences instead, as it offers coverage of the essentials of fluid mechanics in addition to the thermodynamics and the heat transfer coverage in this book. It is recognized that all topics of thermodynamics, and heat transfer cannot be covered adequately in a typical three-semester-hour course, and, therefore, sacrifices must be made from the depth if not from the breadth. Selecting the right topics and finding the proper level of depth and breadth are no small challenge for the instructors, and this text is intended to serve as the ground for such selection. Students in a combined thermal sciences course can gain a basic understanding of energy and energy interactions, as well as various mechanisms of heat transfer. Such a course can also instill in students the confidence and the background to do further reading of their own and to be able to communicate effectively with specialists in thermal sciences.

What Are Thermodynamics and Thermal Hydraulics?

Thermodynamics can be defined in two ways: the science of heat and thermal machines or the science of large systems (i.e., composed of many particles) in equilibrium. In this book, the two aspects will be considered because power plants are thermal machines that produce mechanical energy using heat and mass transfer. As thermal machines, they are subjected to thermodynamic cycles (cf. Sect. 2.9), and as they use fluids to transfer energy from the reactor to the turbine, they are subjected to the laws of thermal hydraulics which is the combination of hydraulics with thermodynamics.The two main concepts in thermodynamics are heat and temperature. These two quantities are defined and used in two ways that reflect the two aspects of thermodynamics: via the efficiency of thermal machines and via statistics (averages) over volumes containing large numbers of particles. These quantities are governed by the first and second laws of thermodynamics. Heat and temperature are related via the concept of entropy, with the fundamental formula:dS=δQrevTdS=δQrevT(2.1)where dSdS is the variation of entropy of the system that receives δQrevδQrev amount of heat energy during a reversible process at temperature T.

The two additional concepts used for hydraulics are the conservation of mass and the conservation of momentum.

OBJECTIVES – Introduction to Thermodynamics and Heat Transfer

This book is intended for use as a textbook in a first course in thermal sciences for undergraduate engineering students in their junior or senior year, and as a reference book for practicing engineers. Students are assumed to have an adequate background in calculus, physics, and engineering mechanics. The objectives of this text are • To cover the basic principles of thermodynamics and heat transfer. • To present numerous and diverse real-world engineering examples to give students a feel for how thermal sciences are applied in engineering practice. • To develop an intuitive understanding of thermal sciences by emphasizing the physics and physical arguments. The text contains sufficient material to give instructors flexibility and to accommodate their preferences on the right blend of thermodynamics and heat transfer for their students. By careful selection of topics, an instructor can spend one-third, one-half, or two-thirds of the course on thermodynamics and the rest on selected topics of heat transfer.
