Summary

A semi-empirical model for condensation on horizontal, integral-fin tubes was adapted to account for "fin efficiency effects". Calculations were made to investigate the effect of tube geometry and material on the "enhancement ratio" for condensation of steam and R11. The best fin spacing was found to be only slightly dependent on the other geometric variables and fin thermal conductivity. The best fin thickness was more strongly dependent on fin thermal conductivity. For the refrigerant the optimum fin thickness was smaller than that currently used in practice. The model gave satisfactory agreement with experimental data for R113 and steam for typical fin geometries.
