Thermal Hydraulic Study of a Single Row Heat Exchanger With Helically Finned Tubes

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.
