The recently published book by the author, "Engineering Heat
Transfer," already dealt with exact computation of heat exchangers
and tube banks. In design c-
putationthisisaccomplishedviacorrectivefactors;thelattermakesitpossibleto
compute the actual mean temperature difference by starting from the
logarithmic onerelativeto?uidsinparallel?oworcounter?ow. As far as
veri?cation computation is concerned, corrective factors were int-
ducedtocomputeacertaincharacteristicfactorcorrectly,
asisfundamentalforthis typeofcomputation. Basedontheabove,
theauthordecidedtoinvestigatefurther, re?ne, andwiden thistopic:

Newtypesofexchangerswereexamined;thecalculationwasre?nedtoproduce

Thescopeoftheinvestigationwasincreased by widening the range of the
starting factors. Furthermore, a greater number of
valuestobeincludedinthetableswasconsidered. Finally,
afewcharacteristicsof
