This well-written book is a useful addition to the large number of textbooks available for heat transfer courses that are taught at the undergraduate level in engineering. It is written as an introductory book for a one-semester course, though the material included is more than what can easily be covered in a semester. It is written in a clear and easy-to-understand style, with a focus on the basic principles of heat transfer. Consequently, advanced topics, solution methods, and applications are generally not covered, since the basic concepts can be brought out by considering relatively simpler problems. Though the emphasis is on analysis, some discussion is devoted to numerical methods, and a few selected computer programs are included. The book stresses problem formulation on the basis of the fundamental principles of thermodynamics and mechanics.

The book starts with the foundations of the subject and discusses the basic concepts that are used for formulating a problem in heat transfer. The basic laws such as Fourier’s law of conduction and Stefan-Boltzmann’s law of radiation are presented. Methods of formulation are discussed, with the inductive formulation approach being adopted for the text. The five steps included in the formulation, involving defining the system, stating the general and particular laws, and obtaining the governing equations and the initial and boundary conditions, are presented in detail. Conduction heat transfer is covered in the next three chapters, starting with steady one-dimensional conduction and progressing through multidimensional to transient conduction. Problems in different coordinate systems and with different boundary conditions are considered. The basic methodology is again stressed and many well-known, classical, and useful solutions are given. Computational methods for conduction follow this treatment, and both steady and unsteady problems are considered for a numerical solution. This chapter shows the importance and usefulness of numerical methods and presents some standard solution strategies.

The basic concepts in convection, including boundary layer flow, dimensional analysis, scales, dimensionless parameters, and governing equations, are presented in Chapter 5. The integral analysis approach is used for obtaining the solutions. Thus, the treatment is somewhat elementary, but it does bring out the basic features of the transport processes. The discussion is mainly directed at the physical nature of the problem and underlying principles, as done earlier for conduction. This is followed, in the next chapter, by empirical correlations for both forced and natural convection. Many important results, with some presented in terms of dimensionless numbers proposed by the first author, are given. The use of these correlations is also demonstrated. The analysis and selection of heat exchangers are discussed in detail in Chapter 7, considering different types of heat exchangers and methods of analysis. Important and well-known results are included.

Radiation heat transfer is covered in the next three chapters. The basic concepts are introduced in Chapter 8, including the quantum mechanics basis for transport and properties of radiation. This is followed by a chapter on radiative exchange in enclosures using view factors, electrical analogy, and the radiosity method of analysis. Gas radiation is presented in the next chapter considering radiation properties of gases, optical thickness, and simple methods to account for gas radiation. This chapter presents several useful results that can be used in practical problems. Finally, phase-change problems are considered in the last chapter. Several interesting results in boiling and condensation are given. Some important material properties, units, charts, and correlations are included in the appendices making it easy to find relevant data for solving exercises in the book.

The presentation is clear, and the treatment is quite satisfactory for an introductory course. It will be a useful textbook for engineering students who have not studied heat transfer, though they have been exposed to courses in thermodynamics and fluid mechanics. Most other textbooks in heat transfer at this level tend to focus on solution methods and results, while also discussing various practical problems to bring out the importance of heat transfer in different fields. The present book is clearly directed at the fundamental aspects and on the formulation of the problem. It serves a very useful and worthwhile role in this capacity. The examples and exercises given in the book help in the presentation and in the understanding of the material, as well as in pointing out the application of these methods to more complicated problems. Introduction to Heat Transfer can certainly be recommended as a textbook for introductory courses in heat transfer.
