Corrected length of fin
WebHere we have to consider the analysis for each fin then evaluate the overall surface consisting of fins and a remaining area without fins. For each fin the cross sectional area A c = π(0.0025 m) 2/4 = 4.909x10-6 m2 and the perimeter p = π(0.0025 m) = 0.007854 m. The corrected length, L c = L + A c/p = 0.03 m + (4.909x10-6 m2) / (0.007854 m ... WebThe corrected length approximation gives very good results when the variation of temperature near the fin tip is small (which is the case when mL $ 1) and the heat transfer coefficient at the fin tip is about the same as that at the lateral surface of the fin. Therefore, fins subjected to convection at their tips can be treated as fins with ...
