Title:Air-Side Performance Characteristics of Round- and Flat-Tube Heat Exchangers: A Literature Review, Analysis and Comparison
Author(s):Park, Y.G.; Jacobi, A.M.
Subject(s):heat exchangers
air-side thermal performance
Abstract:The air-side thermal-hydraulic performance of serpentine-fin, flat-tube heat exchangers is compared to that of conventional plate-fin, round-tube designs for various fin geometries and surface conditions. Heat exchanger performance correlations are obtained through a critical review of literature and complementary analyses. The result shows a clear advantage of flat-tube design under dry, low-Reynolds-number conditions in comparison to round-tube heat exchangers. The parametric effects on heat exchanger performance reported in the literature, the reasons of discrepancies, and the practical ranges of geometrical and operational parameters in applications are identified and summarized in this study.
