Equipping practicing engineers and students with the tools to independently assess and understand complex material on the topic, this text is an ideal precursor to advanced heat transfer courses. Intermediate Heat Transfer discusses numerical analysis in conduction and convection, temperature-dependent thermal conductivity, conduction through a slab from one fluid to another fluid, steady-state heat conduction in a two-dimensional fin, and truncation and round-off errors in finite difference method. Replete with sample problems to clarify concepts, this is an indispensable resource for professionals and seniors and first-year graduate students pursuing tracks in mechanical, aerospace, nuclear, and chemical engineering.

Written for an advanced undergraduate or first-year graduate course, Intermediate Heat Transfer starts with the basics, and puts emphasis on formulating problems, obtaining solutions, and analyzing results using analytical, and numerical methods with the aid of spreadsheets and CFD software. The text employs nondimensionalization as a tool for simplifying the governing equations, developing additional insights into the physics of the problems, identifying the relevant parameters, and arriving at general solutions. It provides comprehensive coverage of the topics and develops the skills for solving heat transfer problems using numerical methods with the aid of spreadsheets and computational fluid mechanics software. Presents coverage of convective, conductive, and radiative heat transfer at the graduate level Provides a balance of analytical and numerical approaches to advanced heat transfer Stresses nondimensionalization throughout the book as a tool for simplifying the governing equations The author presents detailed numerical solutions to many advanced problems using spreadsheets, although the methods presented for obtaining solutions can be can also be implemented using equation solvers and computing environments, or direct programming using languages such as Fortran or C. The text contains a chapter on CFD to provide the necessary background for obtaining and analyzing CFD solutions. It includes a number of step-by-step tutorials for solving more complicated problems using Fluent, both to show how CFD codes are used as well as a further check of some of the more commonly used assumptions. The text also has extensive coverage of heat exchangers, including being the first text to cover the heat exchanger efficiency for the design and analysis of heat exchangers. This approach eliminates the need for complicated charts or equations. The chapter on mass transfer and chemically reactive flows provides the background needed for modeling of combustion problems. This book fills the gap between the undergraduate heat transfer course and specialized advanced courses like conduction, convection, radiation, and mass transfer. Much has changed in the field of heat transfer, in what is taught, and how it is presented. An important change has been a shift away from advanced analytical techniques, to more reliance on numerical solutions, which also broadens the topics that are covered in these courses.

This book describes recent technological developments in next generation nuclear reactors that have created renewed interest in nuclear process heat for industrial applications. The author’s discussion mirrors the industry’s emerging focus on combined cycle Next Generation Nuclear Plants’ (NGNP) seemingly natural fit in producing electricity and process heat for hydrogen production. To utilize this process heat, engineers must uncover a thermal device that can transfer the thermal energy from the NGNP to the hydrogen plant in the most performance efficient and cost effective way possible. This book is written around that vital quest, and the author describes the usefulness of the Intermediate Heat Exchanger (IHX) as a possible solution. The option to transfer heat and thermal energy via a single-phase forced convection loop where fluid is mechanically pumped between the heat exchangers at the nuclear and hydrogen plants is presented, and challenges associated with this tactic are discussed. As a second option, heat pipes and thermosyphons, with their ability to transport very large quantities of heat over relatively long distance with small temperature losses, are also examined.

Developed from the author’s 30 years of teaching a graduate-level intermediate heat transfer course, Analytical Heat Transfer explains how to analyze and solve conduction, convection, and radiation heat transfer problems. Suitable for entry-level graduate students, the book fills the gap between basic heat transfer undergraduate courses and advanced heat transfer graduate courses. The author places emphasis on modeling and solving engineering heat transfer problems analytically, rather than simply applying the equations and correlations for engineering problem calculations. He describes many well-known analytical methods and their solutions, such as Bessel functions, separation of variables, similarity method, integral method, and matrix inversion method. He also presents step-by-step mathematical formula derivations, analytical solution procedures, and numerous demonstration examples of heat transfer applications. By providing a strong analytical background, the text enables students to tackle complex engineering heat transfer problems encountered in practice. This analytical knowledge also helps them to read and understand heat transfer-related research papers.
