A THEORY OF HEAT TRANSFER BY DROPWISE CONDENSATION
Résumé
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.
