Measurements of condensation heat transfer coefficients of binary vapors of R-113 and water on horizontal smooth and integral-fin tubes were made. The experimental results indicate that finned tubes are effective for the enhancement of condensation heat transfer of binary vapors of immiscible liquids. The heat transfer data for R-113/H2O mixture were correlated by the Akers and Turner equation for condensation of vapor mixtures on smooth tubes and by the modified Rose approximate equation for condensation of single vapors on low-finned tubes. The resulting correlation is found to be in satisfactory agreement with experimental data of Teranishi et al. [6] for an azeotropic mixture of carbon tetra-chloride and water on horizontal tubes with triangular fins.
