CG-4 Composition Profile Method for Condensation of Vapor-Gas Mixtures

R. G. Sardesai and J. W. Palen

A new method is developed to predict the heat transfer coefficients during condensation of vapor-gas mixtures. The method is based on the film theory of mass transfer and uses composition profiles along a condenser length to calculate the heat transfer rates. Comparison with the experimental data has shown that the new method can correctly predict the performance of a condenser for the entire concentration range of 0 percent to 100 percent noncondensable gas.
