In the present paper the recent developments in condensation theories
and models for binary droplet growth or evaporation are reviewed. The
applicability of different theories ranging from exact models to analy
tical solutions is discussed. As an overall result it can be stated th
at for slow condensation (or evaporation) even simple linearized appro
aches yield satisfactory approximations. However, in the cases of rapi
d condensation and strong coupling of fluxes, only exact nonlinear exp
ressions accounting for coupled mass and heat fluxes are applicable. (
