This paper combined modified film model and Nusselt’s condensation theory and studies convective condensation heat transfer on a horizontal tube across which moist mixed gas flows horizontally at a certain speed. A theoretical model allowing for gas boundary layer separation was set up and how the liquid film flows and the heat transfers on the tube were presented. The effects of flowing direction on condensation heat transfer are discussed. Results predict that the condensate is so thin that the liquid phase heat resistance can be ignored.
