Abstract
In this study, the fin pitches of L-footed spiral finned tube heat exchangers were determined for maximimum performance index. The experiments were done at various fin pitches (fp = 2.4, 3.2, and 4.2 mm) under the range of high Reynolds numbers (5,000-15,000). The test sections had a parallel and counter cross-flow arrangement having the number of tube row of 2. The two working fluids were the ambient air and hot water. The performance indexes (ζ1, ζ2, and ζ3) were used to analyze the experimental data at different fin pitches. The results show that the optimal fin pitches for L-footed spiral finned tube heat exchangers are 2.4 and 3.2 mm.
