Summary

In this model: 1. The phase equilibrium is established at the vapour-liquid interface, while the bulk vapour is saturated and the bulk liquid is subcooled. 2. The heat transfer coefficients in liquid film and the frictional pressure drop are calculated by the correlations for pure refrigerants proposed by Haraguchi et al. 3. The mass transfer coefficient in the liquid film is infinite, and the mass transfer coefficient in the vapour core is estimated by a correlation that is derived from the Chilton-Colburn analogy correlation. The predicted results are compared with good agreement with the experimental ones for the condensation of HFC-134a, HCFC-123 and HCFC-22/CFC-114 mixtures.
