Heat Transfer
Mechanisms
In Chapter 2, heat transfer was dened as the form of energy transfer that takes place
between two objects that are at different temperatures. The mechanism by which heat
transfer occurs depends on whether there is any material medium between the two
objects and if that medium is moving or not. Three different mechanisms or modes
of heat transfer are conduction, convection, and radiation. An overview of these heat
transfer mechanisms are given in this chapter and more detailed discussions will be
left for Chapters 8 through 13.
