內容試閱:
In the fall of 2009, Elsevier approached
me about possibly taking over as the lead author of this
textbook. After some consider-ation and receipt of encouragement
from faculty colleagues here at the University of Michigan and
beyond, I agreed. The ensuing revision effort then tenaciously
pulled all the slack out of my life for the next 18 months.
Unfortunately, I did not have the honor or pleasure of meeting or
knowing either prior author, and have therefore missed the
opportunity to receive their advice and guid-ance. Thus, the
revisions made for this 5th Edition of Fluid Mechanics have been
driven primarily by my experience teaching and interacting with
undergraduate and grad-uate students during the last two
decades.
Overall, the structure, topics, and tech-nical level of the 4th
Edition have been largely retained, so instructors who have made
prior use of this text should recognize much in the 5th Edition.
This textbook should still be suitable for advanced-undergraduate
or beginning-graduate courses in fluid mechanics. However, I have
tried to make the subject of fluid mechanics more acces-sible to
students who may have only studied the subject during one prior
semester, or who may need fluid mechanics knowledge to pursue
research in a related field.
Given the long history of this important subject, this textbook
at best reflects one evolving instructional approach. In my
experience as a student, teacher, and faculty member, a textbook is
most effective when used as a supporting pedagogical tool for an
effective lecturer. Thus my primary revision objective has been to
improve the text''s overall utility to students and instruc-tors by
adding introductory material and references to the first few
chapters, by increasing the prominence of engineering applications
of fluid mechanics, and by providing a variety of new exercises
more than 200 and figures more than 100. For the chapters
receiving the most attention 1-9, 11-12, and 14 this has meant
approx-imately doubling, tripling, or quadrupling the number of
exercises. Some of the new exercises have been built from
derivations that previously had appeared in the body of the text,
and some involve simple kitchen or bathroom experiments. My hope
for a future edition is that there will be time to further expand
the exercise offerings, espe-cially in Chapters 10, 13, 15, and
16.
In preparing this 5th Edition, some reor-ganization, addition,
and deletion of mate-rial has also taken place. Dimensional
analysis has been moved to Chapter 1. The stream function''s''
introduction and the dynamic-similarity topic have been moved to
Chapter 4. Reynolds transport theorem now occupies the final
section of Chapter 3. The discussion of the wave equa-tion has been
placed in the acoustics sec-tion of Chapter 15. Major topical
additions are: apparent mass Chapter 6, elemen-tary lubrication
theory Chapter 8, and Thwaites method Chapter 9. The sections
covering the laminar shear layer, and boundary-layer theory from a
purely math-ematical perspective, and coherent struc-tures in
wall-bounded turbulent flow have been removed. The specialty
chapters 10,13, and 16 have been left largely untouched except
for a few language changes and appropriate renumbering of
equations. In addition, some sections have been combined to save
space, but this has been offset by an expansion of nearly every
figure caption and the introduction of a nomenclature section with
more than 200 entries.
Only a few notation changes have been made. Index and vector
notation predomi-nate throughout the text. The comma nota-tion for
derivatives now only appears in Section 5.6. The notation for unit
vectors has been changed from bold i to bold e to conform to other
texts in physics and engi-neering. In addition, a serious effort
was made to denote two- and three-dimensional coordinate systems in
a consistent manner from chapter to chapter However, the completion
of this task, which involves retyping literally hundreds of
equations, was not possible in the time available.
Thus, cylindrical coordinates R, φ, z pre-dominate, but r, θ,
x still appear in Table 12.1, Chapter 16, and a few other
places.
And, as a final note, the origins of many of the new exercises
are referenced to individuals and other sources via footnotes.
However, I am sure that such referencing is incomplete because of
my imperfect mem-ory and record keeping. Therefore, I stand ready
to correctly attribute the origins of any problem contained herein.
Furthermore, I welcome the opportunity to correct any errors you
find, to hear your opinion of how this book might be improved, and
to include exercises you might suggest; just contact me at
drd@uraich.edu.
