要約

Of the three 'ideal' types of two-phase condensate pattern observed during the condensation of vapours of immiscible liquids 'channelling flow' is the most likely one to be encountered in industrial equipment. Visual observations of channelling flow encountered during the condensation of heptane/water mixtures on a vertical brass cylinder are reported. A relationship for the determination of heat-transfer coefficient associated with such a condensate pattern is derived. This relationship is then compared with heat transfer data associated with the condensation of heptane/water mixtures on a vertical surface, and of toluene/water and trichloroethylene/water mixtures on a horizontal copper tube.
