Helium was condensed on the wall of a vertical copper tube (14 mm in diameter, 32 mm long) in the experimental range: vapour temperature in the tube -4. 1-5.0 K; heat flux -0.5-86 mW cm-2; temperature differences across a liquid film -0.01-1.3 K; film Reynolds numbers -3-380. It was found that the h

## Abstract This paper discusses the convective condensation of a gas mixture in a vertical tube. A mathematical model was derived by combining a modified film model and Nusselt's condensation theory. The effect of wall temperature on film thickness and interfacial temperature was predicted and fil
## Abstract The convectionβcondensation heat transfer of vaporβgas mixtures in a vertical tube was studied theoretically and experimentally. The effects of the condensation of a small amount of water vapor (8 to 20%) on heat transfer in a vertical tube were discussed. Comparisons show that theoreti
