Abstract: The paper reviews progress in dropwise condensation research from 1930 to the present. Particular attention is given to heat transfer measurements, theory, transition and effects of surface material. Although it has been known since the 1930s that heat transfer coefficients for dropwise condensation of steam are much higher than those for film condensation, there were, until the 1960s, wide discrepancies between the results of different investigators. Subsequently, more accurate measurements have shown good consistency and the mechanism and theory of the dropwise condensation have become better understood. There has been considerable controversy over the magnitude of the so-called ‘constriction resistance’ and the effect of the surface thermal conductivity on the heat transfer coefficient. The balance of evidence suggests that this is only significant at very low heat fluxes and for very small condensing surfaces. Measurements have also been made with sufficiently high cooling intensities to cover...

Delayed frost growth on jumping-drop superhydrophobic surfaces.
TL;DR: It is reported that subcooled condensate on a chilled superhydrophobic surface are able to repeatedly jump off the surface before heterogeneous ice nucleation occurs.

Recurrent filmwise and dropwise condensation on a beetle mimetic surface.
TL;DR: It is shown that the synergistic cooperation in the observed recurrent condensation modes leads to improvements in all aspects of heat transfer properties including droplet nucleation density, growth rate, and self-removal, as well as overall heat transfer coefficient.

Advances in Condensation Heat Transfer
TL;DR: In this paper, the authors introduce various types of condensation and examine the surface wettability of the surface and discuss the transport process at the vapor-liquid interface and the arguments on whether the condensation coefficient takes the value of unity are discussed.

Dropwise condensation—The distribution of drop sizes
John W. Rose,Leon R. Glicksman +1 more
TL;DR: In this article, a simplified model of the drop growth process during condensation was used to predict the average distribution of drop sizes, and the theoretical distribution was compared with measurements [8, 31], a recent computer simulation [32] and an earlier empirical distribution.
