The combined effect of vapour velocity and condensate inundation during condensation on integral fin-tubes: a theoretical analysis.

Author(s) : CAVALLINI A., DORETTI L., LONGO G. A., ROSSETTO L.

Summary

The paper presents procedures to compute the heat transfer coefficient when downwards flowing pure vapours (or azeotropic mixtures) condense on horizontal integral-fin tubes. At first, single tubes are considered, and the suggested procedure takes shear, gravity and surface tension force into account. The method is compared with a vast data bank demonstrating a sound concordance. The second part of the paper considers condensation on tube bundles, also taking the effect of condensation inundation on heat transfer into account. The correlations proposed are compared with available experimental points demonstrating satisfactory concordance.
