"ESDU 84016 gives correlations for calculating the external heat transfer and pressure loss for flow over low-fin tube banks. ""Low-fins"" are fins of limited height formed on the tube outside wall@ typically by cold rolling. The correlations were derived from a regression analysis of experimental data from various sources covering 14 configurations. They are applicable for Reynolds numbers between 1.0E3 and 8.0E5@ fin densities of 11 to 32 fins per inch (425 to 1250 fins per metre)@ with heights of 0.03 to 0.1 inch (0.75 to 3 mm) on tubes of outside diameter 0.5 to 1.25 inch (13 to 40 mm). For 97 results the method predicts heat transfer coefficient with a standard deviation of 6.6 per cent and over 81 results predicts pressure drop with a standard deviation of 7.7 per cent. A practical worked example illustrates the use of data."
