Course Objectives

 

   MAE 311 serves to introduce the student to the many different processes by which energy may be transferred. A list

of the specific topics is provided in the attached Assignment Schedule. In covering this material, there should be three

overriding objectives:

 

(a) The student should appreciate the physical origins of the various transport mechanisms. Moreover, when confronted

     with a particular problem, (s)he should be able to identify the relevant transport processes.

(b) The student should be able to perform engineering calculations for problems involving heat transfer. (S)he should

      know when, and of what nature, simplifying approximations may be made. (S)he should also be able to perform

      the kinds of calculations which lead to a rational design and/or an improved understanding of the performance of

      thermal exchange systems.

(c) A final, yet equally important objective is to develop a positive attitude towards the subject of heat transfer. It is

     incumbent upon the instructor to reveal the vital role that such processes play in the natural and industrial worlds and

     to thereby transmit a sense of excitement for the subject.

 

   The student should leave the course with confidence in his/her understanding of, and ability to apply, the basic

principles. (S)he should also leave with a desire to apply what (s)he has learned and to expand upon his/her

background.

  

 

 

 

COURSE POLICY

 

1.Prerequisites.

   MAE 311 must be preceded by MAE 221. If you do not meet this requirement, see your Lecturer immediately.

 

2.Assignments.

   You are expected to fulfill each assignment in the following manner:

 

(a) The Lecturer will only highlight the materials corresponding to a particular period and work illustrative problems.

     You will do the reading corresponding to a particular period before the scheduled lecture for that period.

(b) Since your Lecturer will constantly be referring to material in the text, you should bring the textbook to class.

(c) Homework problems from the text are due after a week from the date of assignment. See section 1.5 for the homework solution format. You should follow this format in solving all your assigned homework problems.

Homework problems submitted will be graded and returned to you at the end of the following lecture. All problem

solutions will be posted on the webpage of MAE 311 immediately after they are due for your further study.

 

3.Quizzes.

   Class quizzes of duration of 10 minutes may be given periodically in the lecture, generally without prior

announcement, in order to highlight key points and to promote individual participation in the lecture.

 

4.Midterm Exam.

   The exam will be given on the scheduled dates and will cover all assigned material. No make-up exam will be given

except in the event of excusable absences due to illness or serious emergency.

 

5.Final Examination.

   A final examination, given at the end of the course, will cover all material assigned after the Midterm Exam. No

make-up exam will be given except in the event of excusable absences due to illness or serious emergency.

 

6.Attendance.

   Classroom attendance is expected except in cases of illness, emergencies, or other special circumstances. In case of

an absence, a written or email notice should be submitted to the lecturer. You will be held responsible for any material

which is discussed in lecture, whether treated in the text or not. There will be no opportunity for make-up of missed

assignments in the daily work (homework and exercises) except in cases of long term illness or serious emergency.

 

7.Participation.

   You are encouraged to ask questions during the lecture regarding aspects of reading, homework or lecture material

that is unclear to you. In addition, you may be called upon to answer question, to comment on problem solutions,

and/or lead discussions related to the lecture material. Demonstrating reasonable participation will require daily

preparation and staying current with the assignments.

 

8.Grades.

   The course grade will be based on homework, exercise, participation and exam results. The following list gives the

weighting of the various items to be used in the determination of grades for the course:

 

Homework Problems                                                                              20%

Class Quizzes, Attendance and Participation                                            10%

Mid-Term Test                                                                                       30%

Final Examination                                                                                    40%

                                                                                                              ____

Total                                                                                                       100%

 

9.Unethical Conduct.

   Communication between students in solving the homework problems is encouraged. However, each student is

expected to his/her own work in satisfying the homework problem requirements, and failure to do so will result in a

grade of zero for the assignment. Similarly, any student aught copying from a solution manual will have his/her grade of

zero for each separate incident. Any student detected of cheating on an examination will receive a failing grade in the

course, and documentation will be sent to the Dean of Students Office, recommending termination from the University

for a period of no less than one year.
