Radiating Fin Analysis Using an Extended Perturbation Series Solution Technique

摘要

The approach taken by Aziz in Ref. 5 for fin efficiency computations is now readily expanded for cases involving a nonzero radiating heat-sink temperature. The method is simple and easily adapted using Eqs. (5) and (6) along with the values for the expansion terms in Table 2. The accuracy of the fin efficiency using the series expansion method was found to be within 7% when compared to a SINDA fin model for the zero-sink temperature case.
