Résumé

An improved version of author's earlier correlation for heat transfer during condensation in conventional (macro) and mini/micro channels is presented. It has been validated by comparison with a database that includes 40 fluids, diameters 0.08 to 49.0?mm, reduced pressures 0.0008 to 0.946, mass flux from 1.1 to 1400 kgm-2s-1, various shapes (round, rectangular, triangular, etc.), horizontal and vertical downflow. There are 182 data sets from 88 sources. The improved correlation predicts 5100 data points with mean absolute deviation (MAD) of 18.2%. The same data are also compared to other correlations. Their deviations are much greater.
