Lc. Thomas, Heat transfer in fin assemblies: Significance of two-dimensional effects -A reexamination of the issue, J HEAT TRAN, 121(3), 1999, pp. 748-752
The purpose of this paper is to reexamine the significance and nature of tw
o-dimensional effects in fin assemblies. In particular, consideration is gi
ven to concerns expressed in the literature that the standard approach comm
only leads to large errors due to two-dimensional effects. In addition, for
the purpose of establishing a practical means of evaluating the level of s
ignificance of two-dimensional effects, an approximate first-order two-dime
nsional thermal circuit approach to analyzing heat transfer in fin assembli
es is developed.
