ME204: HEAT TRANSFER

Online Free Online Course by  Saylor Academy
Online / Free Online Course

Details

Heat transfer is the thermal energy in transit due to a spatial temperature difference. The topic of heat transfer has enormous applications in mechanical engineering, ranging from cooling of microelectronics to design of jet engines and operations of nuclear power plants. In this course, you will learn about what heat transfer is, what governs the rate of heat transfer, and why heat transfer is so important. You will also learn about the three major modes of heat transfer: conduction, convection, and radiation.  Heat conduction is the transport of heat through a solid body, by vibrations of molecules or in the case of electrical conductors, by movement of electrons from one molecule to another. Heat convection is a process by which heat is transferred through a fluid by motion of fluid. Thermal radiation is the transport of energy between two bodies by electromagnetic waves. In addition to the three main modes of heat transfer, you will also learn about heat transfer during phase changes (boiling and condensation heat transfer).

Primary Resources: This course is comprised of a range of different free, online materials.  However, the course makes primary use of the following materials:

  • MIT: Professors John Lienhard IV and John Lienhard V’s A Heat Transfer Textbook
  • YouTube: Indian Institute of Technology (IIT) Bombay: Professor S.P.Sukhatme and Professor U.N.Gaitonde’s Video Lectures
  • MIT: Professor Z. S. Spakovszky’sLecture Notes on Thermodynamics and Propulsion

You may also find the following tables resourceful as you work through the materials in this course:

  • MIT Opencourseware: Intermediate Heat and Mass Transfer: “Selected Physical Constants” and “Selected Conversion Factors”*

Make sure to click on each “PDF” link in the Study Materials section to download these tables.

Requirements for Completion: In order to complete this course, you will need to work through each unit and all of its assigned materials.  Pay special attention to Unit 1, as this unit lays the groundwork for understanding the more advanced, exploratory material presented in the latter units.  You will also need to complete:

  • Unit 1 Quiz
  • Unit 2 Quiz
  • Unit 3 Quiz
  • Unit 4 Quiz
  • Unit 5 Quiz
  • Unit 6 Quiz
  • The Final Exam

Note that you will only receive an official grade on your Final Exam.  However, in order to adequately prepare for this exam, you will need to work through the resources in each unit.

In order to “pass” this course, you will need to earn a 70% or higher on the Final Exam. Your score on the exam will be tabulated as soon as you complete it.  If you do not pass the exam, you may take it again. 

Time Commitment: This course should take you a total of 112 hours to complete.  Each unit includes a “time advisory” that lists the amount of time you are expected to spend on each subunit.  These should help you plan your time accordingly.  It may be useful to take a look at these time advisories and to determine how much time you have over the next few weeks to complete each unit, and then to set goals for yourself.  For example, Unit 1 should take you 8 hours.  Perhaps you can sit down with your calendar and decide to complete half of the Unit 1 reading (about 2 hours) on Monday night; the remainder of the Unit 1 reading (about 2 hours) on Tuesday night; the Unit 1 lecture on Wednesday night; etc.

Saylor Academy’s mission is to open education to all.

Saylor Academy’s mission is sustained by the continued evolution of an open educational ecosystem, and we are dedicated partners in this movement. Saylor’s commitment to the open education ecosystem is founded not just on open educational resources and open source learning technologies, but also on open access to credentials, and ongoing open learning opportunities.

Guided by these beliefs, Saylor Academy is currently focused on the following projects:

Open Courses: Maintenance and Learner-Centered Improvements

  • A commitment to the OER community means that we’ll continue to replace open access materials with openly licensed ones in an effort to make Saylor courseware as reusable and remixable as possible.
  • Open courses require more instructional supports for learners, so our current improvements focus on ensuring better and more frequent opportunities for Saylor students to practice what they’re learning.

Open Credentials: Adding New Opportunities and Bolstering Existing Ones

  • We’re working on expanding our suite of Saylor Direct credit recommended exams, and we’re also keen on working with university partners to develop innovative and flexible partner degree launching and completion programs. ...
