In addition to the two different condensation patterns revealed respectively in n ‐pentane (bubble)/glycerol and water (bubble)/silicone oil systems in the authors' previous study (1979), a third pattern has been found in methanol (bubble)/silicone oil system: a condensate appears at the rear part of the bubble surface as several blunt drops, turns into a conical tail through coalescence to each other, and finally drops out from the bubble. The possible mechanism as well as the heat transfer characteristics of the condensation process are discussed.
