Rates of heat transfer have been measured on a water-cooled flat plate promoting film condensation as steam and mixtures of steam and air flowed over it. The rates of heat transfer decreased as the angle of the plate to the horizontal was reduced and as the concentration of air was increased. A notable observation was that comparison of results for the upward and downward facing cases showed that the heat transfer rates with pure steam are higher for an upward facing plate than for a downward facing one. However, with air present in the steam, this trend is reversed. In the case of pure steam, the test results show good agreement with predictions made using the Nusselt theory.
