Both mass transfer in the gas phase and heat transfer in the liquid phase are examined experimentally for gravity-controlled condensation of ethanol and water vapor mixtures on a vertical surface. Some flow patterns of the condensate are observed in relation to the measured concentration of condensate and the heat flux. The departure from the smooth-film-wise condensation is considered to be related to the local fluctuation of surface tension over the condensate film. For the gas-phase mass transfer, the laminar boundary layer theory, applied taking into consideration the increased mass flux, is approximately valid even for the case of drop-wise condensation.
