The changes in content are more significant and at more than one level.
New topics covered in the second edition are convection with change of phase
(condensation, boiling, melting), the cooling of electronic packages by forced
and natural convection, lubrication by contact melting, and several examples of
conjugate heat transfer, i.e., convection coupled with conduction or radiation.
I augmented most chapters with results, namely, formulas, tables, charts, and
appendixes that are recommended for use in engineering design work. And,
speaking of design, many of the new problems at the end of chapters refer to
basic principles of thermal design.
