Huisseune, Auteur ; C. T'Joen, Auteur ; P. Brodeoux, Auteur Article en page(s) : pp. [061801-1/8] Note générale : Physique Langues : Anglais (eng) Mots-clés : Helical  fin  Single  row  Heat  exchanger  Heat  transfer  Friction Index. décimale : 536 Chaleur. Thermodynamique Résumé : In this study, the heat transfer and friction correlation of a single row heat exchanger with helically finned tubes are experimentally determined. The transversal tube pitch was parametrically varied. A detailed description of the test rig and the data reduction procedure is given. A thorough uncertainty analysis was performed to validate the results. The proposed heat transfer correlation can describe 95% of the data within ±11% and shows a 4.49% mean deviation. The friction correlation predicts 95% of the data within ±19% with a mean deviation of 6.84%. The new correlations show the same trend as most correlations from open literature, but none of the literature correlations are able to accurately predict the results of this study.
