Resumo

Two-phase condensates produced during the condensation of vapours of immiscible liquids are very complex. However, they can generally be considered to be characterized as one of three 'ideal' types; film-drop, standing-drop and channelling. The type of condensate produced has a controlling effect upon the rate of heat transfer achieved during condensation.

Heat-transfer data associated with a standing-drop condensate are discussed. Heat flux is found to have a marked effect upon such a pattern and subsequent heat-transfer coefficients. A computer simulation of heat transfer with a standing-drop pattern is described.

A consideration of heat-transfer data for specific patterns demonstrates that many of the apparent anomalies appearing in the literature can be explained by differences in pattern.
