Sinopsis

The paper presents a new theory of heat-transfer by dropwise condensation in the absence of non-condensing gases. The authors consider the heat-transfer arising from condensation on a single drop, and by means of an assumed distribution of drop sizes, deduce the mean heat-transfer rate for the whole surface. The three principal physical phenomena considered in the evaluation of the heat-transfer through a single drop are:
(1) The effect of surface tension on the relations between the temperature and saturation pressures for either side of a curved interface.
(2) Conduction through the drop.
(3) Dissipation associated with matter transfer by condensation.
The theory is compared with recent experimental results of various workers.
