INTRODUCTION TO ENGINEERING HEAT TRANSFER
Introduction to Engineering Heat Transfer
These notes provide an introduction to engineering heat transfer. Heat transfer processes set limits
to the performance of ponents and systems and the subject is one of an enormous
range of application. The notes are intended to describe the three types of heat transfer and provide
basic tools to enable the readers to estimate the magnitude of heat transfer rates in realistic aerospace
applications. There are also a number of excellent texts on the subject; some accessible references
which expand the discussion in the notes are listen in the bibliography.
