Abstract By applying the Le Fevre-Rose theory to dropwise condensation heat transfer on a vibrating heat transfer surface，the quantitative and qualitative changes in the heat transfer characteristics of dropwise condensation on a sine vibrating vertica1 surface in the gravity direction were investigated thretica11y. As a result, when the relationa1 equation of the falling limit droplet diameter of a single droplet on the vibrating vertical surface obtained in past studies of authors was applied to the maximum droplet diameter in the Le Fevre-Rose theory，the theoretica1 value calculated by the method and the experimental value were roughly matched. Therefore, in a limited extent, the quantitative and qualitative dropwise condensation heat transfer characteristics on the vibrating vertica1 surface and its increasing rate cou1d be calculated theoretica11y 　　　Keywords [Dropwise condensation, Heat transfer characteristic，Vibrating vertical surface，Gravity direction，　　　　　　　　　　　　　Theoretica1 analysis]
