A survey of the state of data for condensation of metal vapors is presented and includes a discussion of the influence of measurement precision and traces of non-condensable gas on the observed results. A careful review of data suggests that the condensation coefficient σ is very high, near 1.0, in the absence of non-condensable gas and that most condensation test systems are plagued to a greater or lesser degree by the presence of traces of non-condensable gas.

A theoretical model is developed for prediction of the condensation coefficient on horizontal integral-fin tubes for both high and low surface tension fluids. The model includes the effects of surface tension on film drainage and on condensate retention between the fins. First, the fraction of the tube circumference that is flooded with condensate is calculated. Typically, the condensation coefficient in the flooded region is negligible compared to that of the unflooded region. Then the condensation coefficient on the unflooded portion is calculated, assuming that surface tension force drains the condensate from the fins. The model is used to predict the R-11 condensation coefficient on horizontal, integral-fin tubes having 748, 1024, and 1378 fpm. The predicted values are within ±20 percent of the experimental values.
