Fundamentals of heat and mass transfer 7th edition

Fundamentals of heat and mass transfer 7th edition



The content of the text has evolved over many years in response to a variety of factors.
Some factors are obvious, such as the development of powerful, yet inexpensive calculators
and software. There is also the need to be sensitive to the diversity of users of the text, both
in terms of (a) the broad background and research interests of instructors and (b) the wide
range of missions associated with the departments and institutions at which the text is used.
Regardless of these and other factors, it is important that the four previously identified
learning objectives be achieved.
Mindful of the broad diversity of users, the authors’ intent is not to assemble a text whose
content is to be covered, in entirety, during a single semester- or quarter-long course. Rather,
the text includes both (a) fundamental material that we believe must be covered and (b) optional material that instructors can use to address specific interests or that can be
covered in a second, intermediate heat transfer course. To assist instructors in preparing a
syllabus for a first course in heat transfer , we have several recommendations.
Chapter 1 Introduction sets the stage for any course in heat transfer. It explains the

linkage between heat transfer and thermodynamics, and it reveals the relevance and rich-
ness of the subject. It should be covered in its entirety. Much of the content of Chapter 2

Introduction to Conduction is critical in a first course, especially Section 2.1 The Conduc-
tion Rate Equation, Section 2.3 The Heat Diffusion Equation, and Section 2.4 Boundary

and Initial Conditions. It is recommended that Chapter 2 be covered in its entirety.
Chapter 3 One-Dimensional, Steady-State Conduction includes a substantial amount of
optional material from which instructors can pick-and-choose or defer to a subsequent,
intermediate heat transfer course. The optional material includes Section 3.1.5 Porous
Media, Section 3.7 The Bioheat Equation, Section 3.8 Thermoelectric Power Generation,
and Section 3.9 Micro- and Nanoscale Conduction. Because the content of these sections is
not interlinked, instructors may elect to cover any or all of the optional material.
The content of Chapter 4 Two-Dimensional, Steady-State Conduction is important
because both (a) fundamental concepts and (b) powerful and practical solution techniques
are presented. We recommend that all of Chapter 4 be covered in any introductory heat
transfer course.

The optional material in Chapter 5 Transient Conduction is Section 5.9 Periodic Heat-
ing. Also, some instructors do not feel compelled to cover Section 5.10 Finite-Difference

Methods in an introductory course, especially if time is short.
The content of Chapter 6 Introduction to Convection is often difficult for students to
absorb. However, Chapter 6 introduces fundamental concepts and lays the foundation for
the subsequent convection chapters. It is recommended that all of Chapter 6 be covered in
an introductory course.

Chapter 7 External Flow introduces several important concepts and presents convec-
tion correlations that students will utilize throughout the remainder of the text and in subse-
quent professional practice. Sections 7.1 through 7.5 should be included in any first course

in heat transfer. However, the content of Section 7.6 Flow Across Banks of Tubes, Section

7.7 Impinging Jets, and Section 7.8 Packed Beds is optional. Since the content of these sec-
tions is not interlinked, instructors may select from any of the optional topics.

Likewise, Chapter 8 Internal Flow includes matter that is used throughout the remain-
der of the text and by practicing engineers. However, Section 8.7 Heat Transfer Enhance-
ment, and Section 8.8 Flow in Small Channels may be viewed as optional.

Buoyancy-induced flow and heat transfer is covered in Chapter 9 Free Convection.
Because free convection thermal resistances are typically large, they are often the dominant
resistance in many thermal systems and govern overall heat transfer rates. Therefore, most
of Chapter 9 should be covered in a first course in heat transfer. Optional material includes
Section 9.7 Free Convection Within Parallel Plate Channels and Section 9.9 Combined
Free and Forced Convection. In contrast to resistances associated with free convection,
thermal resistances corresponding to liquid-vapor phase change are typically small, and

they can sometimes be neglected. Nonetheless, the content of Chapter 10 Boiling and Con-
densation that should be covered in a first heat transfer course includes Sections 10.1

through 10.4, Sections 10.6 through 10.8, and Section 10.11. Section 10.5 Forced Convec-
tion Boiling may be material appropriate for an intermediate heat transfer course. Similarly,

Section 10.9 Film Condensation on Radial Systems and Section 10.10 Condensation in
Horizontal Tubes may be either covered as time permits or included in a subsequent heat
transfer course. We recommend that all of Chapter 11 Heat Exchangers be covered in a first heat trans-
fer course.

A distinguishing feature of the text, from its inception, is the in-depth coverage of radi-
ation heat transfer in Chapter 12 Radiation: Processes and Properties. The content of the

chapter is perhaps more relevant today than ever, with applications ranging from advanced
manufacturing, to radiation detection and monitoring, to environmental issues related to

global climate change. Although Chapter 12 has been reorganized to accommodate instruc-
tors who may wish to skip ahead to Chapter 13 after Section 12.4, we encourage instructors

to cover Chapter 12 in its entirety.
Chapter 13 Radiation Exchange Between Surfaces may be covered as time permits or
in an intermediate heat transfer course.
The material in Chapter 14 Diffusion Mass Transfer is relevant to many contemporary
technologies, particularly those involving materials synthesis, chemical processing, and
energy conversion. Emerging applications in biotechnology also exhibit strong diffusion
mass transfer effects. Time permitting, we encourage coverage of Chapter 14. However, if
only problems involving stationary media are of interest, Section 14.2 may be omitted or
included in a follow-on course.
