Understand the basics of Heat pipe, Boiling and Condensation[3] 5 Estimate radiation heat transfer between black body and gray body surfaces[4]
Lecture 2 BASICS OF HEAT TRANSFER 2 1 SUMMARY OF LAST WEEK LECTURE • There are three modes of heat transfer: conduction, convection and radiation
In all of these situations and many others, we can identify three basic mechanisms of heat transfer They are conduction, convection, and radiation
way of presenting the essentials of heat transfer along with many examples The first edition of this book was published in 2003 At the University of
Radiation: The heat transfer from one body to another without any transmitting medium It isan electromagnetic wave phenomenon Example: Radiation sun to earth
Figure 3 1 Conduction, convection and radiation heat transfer modes Note that this equation provides a heat flux, that is, the rate of heat transfer per
Basic Laws of Heat Transfer; Thermal Conductance and Resistance All the three modes of heat transfer, conduction, convection and radiation, can be described in
Note: Alm comes into play when the area for heat transfer at the two ends across Basics of Convection Basics of Radiation Heat Transfer
While teaching heat transfer, one of the first questions students Note:??Since this is a vector equation, it is often convenient to work with one
The basic mechanisms of heat transfer have been ex- plained and some quantitative relations have To do this, note that the heat transfer, Q, must be
