Abstract
An improved version of the present author's earlier correlation for heat transfer during condensation in conventional and mini channels is presented. It has been validated by comparison with a database that includes 51 fluids (water, refrigerants, chemicals, cryogens), diameters 0.08 to 49.0 mm, reduced pressures 0.0006 to 0.949, mass flux from 1.1 to 1400 kgm−2s−1, various shapes (round, rectangular, triangular, etc.), single and multi-channels, annuli, horizontal and vertical downflow. The data are from 130 sources. The improved correlation predicts 8298 data points with mean absolute deviation (MAD) of 17.9 %. The same data are also compared to other correlations. Their deviations are much greater.
