Abstract
Both azeotropic and nonane rich vapours of the steam/n-nonane system were condensed at atmospheric pressure over a copper vertical flat plate and a single column of six horizontal copper tubes. Over the whole range of temperature driving forces channelling flow of condensate occurred on the oxidised surface and standing drop film flow on the same surface free of oxide. Continuous tests were run for several weeks with the surface in both conditions before collecting data. The results are compared with a generalised channelling flow model and a simple model of standing drop film condensation.
