Forced convection film condensation on a horizontal tube: effect of surface temperature variation.

Type of article: Article

Summary

In the paper it is shown that, when a simple surface shear stress approximation, which gives satisfactory values for the mean heat-transfer coefficient for an isothermal tube, is adopted with variable wall temperature, higher mean surface heat-transfer coefficients are obtained. This seems to be in contradiction with results of conjugate (vapour-to-coolant) solutions which predict variable wall temperature and lower mean surface heat-transfer coefficients. Reasons for this apparent anomaly are advanced.
