Heat Transfer (6th ed.). Hoboken, NJ: John Wiley & Sons, Inc., ISBN 978-0470-50196-2.
Pre-requisites:
MATH 261 with C or better, MAE 320, MAE 331 or 335
Course Objectives:
The objective of this course is to provide students with the necessary knowledge of the
three modes of heat transfer - conduction, convection and radiation and the basic laws
relevant to each mode. The course will provide students with the methods needed to
formulate analytical and numerical solutions to heat transfer problems. Applications
will be presented and discussed.
Learning Outcomes:
The course addresses four primary pedagogical learning outcomes.
ABET Outcomes:
•
Graduates will demonstrate an understanding of the physical concepts of heat
transfer, modes of heat transfer, rate equations, conservation equations and
analogies between heat transfer and other engineering disciplines.
•
Graduates will develop and demonstrate enhanced analytical, mathematical,
numerical and experimental skills in applied heat transfer concepts.
•
Graduates will be able to establish the relationship of heat transfer to thermal
system behavior and the design process.
MAE 423 is a key course for any of the key ABET Outcomes:
C
An ability to design a system, component or process to meet desired needs
H The broad education necessary to understand the impact of engineering
solutions in a global and societal context
J
A knowledge of contemporary issues
MAE 423 also supports the following ABET Outcomes
A
B
An ability to apply knowledge of mathematics, science and engineering
An ability to design and conduct experiments, as well as to analyze and interpret
data
E
An ability to identify, formulate and solve engineering problems

Grading:
Grades are assigned based on performance, NOT on “effort”. Grades for projects are
assessed based on overall quality of document and engineering considerations as well
as on relative comparison with the rest of the class.

Professional attitude and conduct is expected from all students.
•
No cell phones or MP3 Players allowed in class.
•
Disruptive behavior in class will not be allowed (that includes reading newspaper,
falling asleep, using music players and talking).
•
Assignments must be submitted IN CLASS at the time they are due (NOT
responsible for assignments submitted in mailbox, in the halls or under my office
door).
•
Late assignments will be penalized 10% per day.
•
Late assignments will not be accepted.
•
All assignment problems must be presented on individual pages on plain white
paper or engineering pad paper (each page must have DATE and NAME).
•
Missing an exam with no reasonable justification will result in a Zero grade for that
exam.
•
Completeness, neatness and legibility in assignments, exams and projects are
mandatory. Sloppiness will be penalized at instructor’s discretion.
Class attendance contributes significantly to academic success. Excessive absences
may jeopardize your grades or even your ability to continue in their courses. The basis
for an excused absence will follow University policy. Students who are absent from
class for any reason are responsible for all missed work. Students who miss a quiz or
an exam will not be permitted to make it up, except in the case of a documented
family or other legitimate emergency or as required by University policy.
Special Concern Days: WVU recognizes the diversity of its students and the needs of those who wish to be
absent from class to participate in Days of Special Concern, which are listed in the
Schedule of Courses. Students should notify their instructors by the end of the second
week of classes or prior to the first Day of Special Concern, whichever is earlier,
regarding Day of Special Concern observances that will affect their attendance.
Further, students must abide by the attendance policy of their instructors as stated on
their syllabi. Faculty will make reasonable accommodation for tests or field trips that a
student misses as a result of observing a Day of Special Concern.

Reading Assignments: The planned course content shows the material to be studied in this course. It is
valuable if students read the text material before each class meeting. It is essential to
keep up to date and see your instructor promptly if you have any difficulty. About 1
hour of work outside of class is needed per class meeting.
Homework:
Generally, homework will be due about once each week (as announced in class).
Assigned homework will be given in class and may include problems from the textbook
and from other sources. Help on homework will be available during office hours or by
appointment. The TA will also be available during posted office hours to provide
assistance and answer questions. All homework will be collected at the beginning of
class. Late homework will not be accepted. Solutions for homework assignments will
be distributed via email.
Collaboration on homework is strongly encouraged to the extent that it promotes
mutual understanding by all involved. It is expected that all work submitted for
grading will be the work of the individual, no common responses are allowed. Copying
of homework solutions from another student or a published solution will result in a
grade of zero on the assignment. Homework is meant to strengthen the concepts in
the course and is EXTREMELY important, both in your understanding of the material.
Written homework should be submitted properly headed (name, date, course and
assignment number), professional and should be neat and legible. Points may be
deducted from improperly prepared and/or sloppy homework. The final page of this
syllabus details homework solution format.

Academic Integrity:
The integrity of the classes offered by any academic institution solidifies the
foundation of its mission and cannot be sacrificed to expediency, ignorance, or blatant
fraud. Therefore, I will enforce rigorous standards of academic integrity in all aspects
and assignments of this course. For the detailed policy of West Virginia University
regarding the definitions of acts considered to fall under academic dishonesty and
possible ensuing sanctions, please see the Student Conduct Code at
http://www.arc.wvu.edu/rightsc.html. Should you have any questions about possibly
improper research citations or references, or any other activity that may be
interpreted as an attempt at academic dishonesty, please see me before the
assignment is due to discuss the matter.
Inclusion Statement:
The West Virginia University community is committed to creating and fostering a
positive learning and working environment based on open communication, mutual
3
respect, and inclusion.
If you are a person with a disability and anticipate needing any type of accommodation
in order to participate in this class, please advise me and make appropriate
arrangements with the Office of Accessibility Services (293-6700). For more
information on West Virginia University's Diversity, Equity, and Inclusion initiatives,

HOME WORK SOLUTION
EXAMPLE PAGE
KNOWN:
State concisely what is known about the problem.
FIND:
State concisely what must be found.
SCHEMATIC:
Draw a schematic of the physical system being considered. Label important variables. If application of the
conservation laws is anticipated, represent the appropriate control volume or control surfaces by dashed lines.
Be sure to identify processes associated with control volume/surfaces.
PROPERTIES:
List the solid and/or fluid thermophysical properties used in your solution. Identify the table from the Text and
especially the temperature at which the property was selected.
ASSUMPTIONS:
It is important that you put all the assumptions in one place so that they can be reviewed. At the outset, some
assumptions may be obvious, like “steady-state conditions,” etc. But as you begin to model more complicated
systems, the assumptions are extremely important to the logic of your analysis.
ANALYSIS:
Provide in sentence format, comments that make clear the logic and organization of your analysis. Be sure to
identify by numbers any figures or equations taken from the Text.
