A quasi-static nucleation model. 1. Homogeneous nucleation

A homogeneous nucleation model is considered. It is based on the idea that in the parent phase, a quasi-static distribution is formed of the new phase nuclei as an effect of mechanisms of their generation and destruction. An estimate is presented of quantity and of generation rate for viable nuclei in supersaturated vapor and supercooled water. The calculation results are compared against earlier experimental data obtained by different authors.
